Hello! New to BAR

Hello everyone, I’m Adam Mollica. I’m brand new to BAR and have only been in the hobby for about two months now. I have a 20 gallon long tank as I only have limited time and funds, but I definitely will upgrade eventually (I’m still a broke college student for a little longer). I’m so glad to have found such a community of refers, especially with the extensive DBTC system. I hope to have many tanks in the future, and I would love to use these to help spread corals (and maybe even fish/inverts) to new hobbyists.

When it comes to forums, I’m definitely more of an observer. I will like or react to photos, but I tend to only comment when I have a question or have important information/advice. I think I will become increasingly active here as I progress through the hobby, but I thought I should mention my activity on the forum may not always represent my activity in the hobby.

So far my 20 gal has 1 Ocellaris clown, 1 Skunk cleaner shrimp, 1 Yellow watchman goby paired with 1 Tiger pistol shrimp, 1 Hermit crab, 1 porcelain crab, and 2 snails (1 trochus 1 astraea).
I will get another oc. clown, but I’m considering getting a different color pattern (morph?).

For Coral I have 1 Rose bta (I know its not a coral, and I understand the potential risks), A few Green finger/tree leathers, 2 green hairy mushrooms (Rhodactis?), a pink finger leather coral, a War coral Favia, some GSP, and and an unknown sps coral that was given to me as a bare skeleton and has since recovered. I think this is either a lythophyllon or leptastrea, but I could use some help identifying it. I could also use help with the two leather corals, one is a neon green “tree” and one is a coral/pink harder coral, but I’ve seen both labeled “finger leather”. I do have photos of the parent coral if needed.

Recently, I had an oc. clown pass away (I had 2) and I returned a starfish to the lfs. The clown randomly began “gasping” and acting lethargic, so I immediately did a ~35% water change and ensured that my powerhead disturbing the surface plenty. Over the next few days be was less and less mobile, staying in the corner on the ground on his side. I did my best to spot feed him but he refused to eat and eventually passed. I couldn’t see any visual issues at all and my other clown has been totally fine, so not sure what happened exactly. I also did a water test in the beginning but didn’t see any big changes or scary numbers (more in my tank log). I also had a green brittle star, about 7” across who mostly hung out in the tunnel. He was really fun to watch, but the clowns stayed far away and he kinda dominated the best real estate in the tank, so he had to go.

Also, I know I have a hair algae problem. I am ok with this for now as the new livestock change should more efficiently process food added to the tank. Also, I hope to get a baby Blue Tang soon (only for a couple months, more on this in my tank log) who should feast on the algae. I am also considering something else like a lawnmower blenny (suggestions welcome), although I am hesitant to add anything that would limit my choice in a centerpiece fish.

If anyone has any stocking recommendations or advice, please let me know.

Thanks for any advice or ideas you may have to offer, I look forward to exploring more of BAR!

Welcome to BAR! Cool tank btw. I still consider myself a new reefers too. There is a lot to learn here and in this hobby in general. So many rabbit holes of research and it seems, just as many ways to accomplish your goals. Thankfully, there are so many reefers here willing to help that have decades of experience to help us along the way. So don't be afraid to ask.

I would not go down the route of getting a blue tang. It's just not meant to be put in a tank that small. One thing you will find here, is at the end of the day, we would prefer to do the right thing for the animals we keep.
 
Hi
And welcome to our place in space.
You have made a very wise decision to become a $upporting member

Now for some support from us:
IMHO
Bottom right corner there is a rock with a three on it...take it out!
Unless is a calcium carbonate based rock, it doesn’t belong in your reef aquarium.
Also, do I see some kind of toy or other ornament get it out of that tank
You mentioned a blue tang...no no no, your tank is way too small.
What is the filtration on there?
 
Welcome to BAR!

Did you de-rim your 20 long, or did you purchase one without a top rim? Either way nice tank:)

A baby blue tang might be ok in that tank, but babies grow up, especially quickly if you're feeding them well. I don't recommend getting any tang of any size in a 20 gallon if you don't already have a destination in mind for when it gets older.

Good eye!

I get it that aesthetically it's not for everyone. But do they degrade in a reef aquarium in some way? I'm with you, I'm genuinely curious if there are cited sources of toxins released by these. Personally, I wouldn't chance my tank with a painted ornament that is supposed to be "aquarium safe".

Also, I appreciate you being direct and mentioning it. I didn't want to be the one that said it.
 
I'm not totally convinced that plastic ornaments are actually harmful. Consider all the FOWLR tanks, or tanks close to it, with massive fake coral installations. The fish don't seem to mind so much, at least. Even in full reef tanks, given the amount of 3D prints, plastic equipment, acrylic tank, rubber-ish cables, glues, magnets sealed in resin, etc that go in the water, clearly some plasticy materials are safe - and I'd assume that decor manufacturers choose those materials for aquarium ornaments. I think they're OK
 
Welcome, Adam. As you can already tell, we do not shy away from encouragement and enablement but also discouragement if needed.

A 20-gallon tank will be a better coral tank than a fish tank. Just mention this to manage expectations. We all like tangs here, but this will need arguably 90 gallons up—often much more.

There are some nice fish that fit—a court jester goby is one. Purple firefish is another alternative. Maybe a royal gramma.

The hair algae is normal for two months. If things are stable, you can add a small tuxedo urchin, but you need to help her in the beginning and manually remove the algae as much as possible. She prefers the algae fresh.

Looking forward to reading your journal. Feel free to reach out with any questions.
 
Welcome to bar, i see he's already commented above but seeing you have a 20gallon tank. Check out @tribbitt click link below to see his tank journal it should be really inspiring seeing whats possible in a tank same as yours.


Please feel free to comment and ask any question no matter how dumb it seems to you. I still ask them myself lol. We all start off with limited knowledge and once we think we know something this hobby is great at teaching you there is always more to learn hence the hobby is challenging yet rewarding at the same time.

I wish you the best of luck.

Welcome!

Agree the rock in the far right/front looks like maybe a river rock or land rock? Not always reef safe, I’d take it out.

Unpainted plastic without metal or anything else in general is reef safe but up to you if it’s aesthetic or not. Ornaments made for freshwater are not always reef safe. I personally wouldn’t use any that wasn’t specifically made to be used in reef tank or straight off a 3D printer.

If you don’t already have an auto top off, that’s your first upgrade. There are cheap/small ones now.

A small skimmer will probably be a lot more useful than the freshwater type hang on filter you have. Since you don’t have a sump or a skimmer you should consider at least an airstone/airpump. I’m worried you don’t have enough air turnover/oxygenation.

I bet you need more flow. Another inexpensive pump on the other side would help. The water everywhere should be moving.

What city are you in? A lot of us have extras of the stuff I’m listing off.

Hope you find all this helpful, that’s the spirit in which it’s being given!
 
Welcome @Adam M ! I made the same mistake of adding a "temporary" nickel sized blue tang to try and handle algae. 10 years later it still was in my tank until I gave it to someone with a 200gal+ (the size they should be in). They don't do much at all eating wise and you're better off with manual removal (brush) and a turbo snail until the rocks mature. A lawnmower blenny will get lazy and just eat whatever you feed your clown plus the film algae on rocks and glass.

Thanks for the recommendations. Filtration is a Fluval AquaClear 30 HOB, full system info is in my new tank journal post. I may get a small skimmer soon to help with gas exchange. That rock on the right was collected from my local beach, and I did wash it pretty good before putting it in the tank, but you're probably right. I will get a new rock structure soon, I could use a cool island, maybe something with barnacles. It would be cool to get some barnacle blennies.

Thank You! I did de-rim it, the rim didn't have a center cross member so I figured it wouldn't change much. I kept the ends with some modification so I could still use the glass top.

Ya my plan was only a small baby tang, and to find line up a forever home long before it needed to move. After all the responses and advice online, while I still think I could do it without hurting it, I don't think I'm going to go down this route. I would rather play it safe while I'm new and don't want to effect the other fish.

This is the stance I currently have. I've seen fish stores use fake structures and even red solo cups in long-standing tanks. I'm not married to it either though, if I suspect any issues it will be gone. I will likely remove it before corals grow and trap it. It was a fun shelter for the brittle star.

Thanks for the recommendations! I've been convinced to not pursue a tang, seems it will be a fun goal when I build a larger tank. I looked at an urchin but didn't want it picking up loose frags, although with the pistol shrimp now I'm learning its best not to have loose frags in general. May have to get one after I establish everything on the rockwork. My first tank journal is up now, will post another (bringing it to date) hopefully tomorrow.

Thanks for the advice! Manual top off hasn't been terrible because of the glass top, although the coral (and I) would probably prefer ATO in the long run. I have avoided adding things that need a sump (or distilled water tank) as the desk the tank is on does not have a hole for pipes to run inside, and I cannot drill one. I am considering a small sump behind the tank though, which I may be able to mostly hide. Here I could also hide an ATO tank.

I am also concerned about gas exchange, I have modified my powerhead and diy cover setup a few time with this in mind, keeping the powerhead pointed at and close to the surface. I'm strongly considering a small skimmer to address this, I'm trying to decide if a HOB skimmer would suffice, or if I need the sump. I had not really considered an air stone though, does anyone know any (mostly) silent air pumps? That may be a decent middle-ground.

Flow is something I need to improve, I definitely want something with programs so the flow is not always the exact same. I'm pretty handy with electronics and have a lot of experience controlling motors so I think this is where I will get creative. If I find something good on marketplace I will also snag it.

I'm located in Benicia in the north bay, I'm always checking marketplace/craigslist but would greatly appreciate any donations. I am in search of a PAR meter and CO2 checker to borrow.
