I agree in keeping DBTC how it is for the purposes of "backing up" your coral, though I agree with @Coral reefer that perhaps there could be some way to organize parallel but distinct chains of the same coral type. I also agree that specific lineage is of some importance; I have a chain for a...

I have seen tangs in shop frag tanks, but I feel like they don't belong in a shallow tank. And they don't need rockwork to hide and sleep in? And won't they grow too large? Could one of those tangs be moved into a 105g in the future without causing problems? I'm feeling stressed about it, but...

Seeking suggestions and experience from those who have housed fish in a shallow tank, say 12" or less in height. I currently have a 10" H lowboy roughly 50g and am about to reset a 22g bookshelf tank (3' long). My questions include fish jumping out, fish not stressed out by the shallow depth...

12-year-old boy. Enough said. Actually, some 7th graders in an accelerated science class went on the trip but I do not teach that grade. I have several of them in my marine science elective class but we have been too busy to talk about it and I don't want to make the rest of the kids feel sad...

Registered and looking forward to it! Topic is perfect for me and my tanks at this time - ha!

Student saw this today at Cal Academy. Said it looked like it might have birdlike feet under it and might have dragon in the name. Anybody know what it is? I have a video clip of it moving and it is super cool

Trying to rearrange an out-of-town weekend bc I really want to attend!

So sorry for this, Eric! Thank you for the reminder to everyone.

I have seen them for sale in shops dead or mostly so. They should be swimming around wildly. If lid was kept on or they were in the fridge, they are likely dead. They are very hardy though, so I would dump them into a bowl of SW at room temp and see what happens. If you have a sieve, maybe get...

:mad: Favia looked fine on Friday. So that orange Lobo (?) stung it, I guess. Previous post shows how close it was. We moved it to the side as pictured here. Not sure anything would eat Favia. That Lobo was a tiny orange and green frag in 2016 and it has lived through some tank ordeals. I...

NICE! Question: what kind of swell is there up at the top of the tank? How much does the water height change at the top edge? I have never tried anything interesting with flow and have always had dead spots, I think. Also have always been worried about stress on tank from back and forth motion...

Are your layers connected or will you add a separate layer once the top one is grown over? A couple students asked if they could stack frag discs "like a fancy cake" with the base getting larger at the bottom of the stack, but most of our discs are thin. Interested to follow your progress!

Thanks. Been a problem for a few years bc Lightspeed stopped making them and used an alternate source but now offer nothing. I waited months a year or so ago on backorder, then the battery I got from CDW-G stopped holding charge (and no longer carried) or it's something wrong in my equipment. I...

Unrelated to reefing, but I need a replacement audio system microphone NiMH battery - NH2A27. Specs: 1.4 or 1.5V, 2700 mAH, 0.57"x1.99"/14.5x50.5mm. (~AA size) An online blog said it could use "any NiMH rechargeable battery but you’ll need to remove the branding wrapper off the battery." Do not...

Too bad that sponge will irritate the coral - great photo and sponge!

Here is ours. It eats green algae and wiry algae:

Green zoas in Pleasant Hill need a home. It is probably on your way to Concord/Clayton if you are heading out that way Thursday or Friday. Might be able to get a better pic Thurs.

What we have is nuisance algae (in the eye of the beholder) of all types in one tank as well as an overrun of cyano and foraminiferans in another tank. I have to say when school started and students fed tanks much more food at one time than I did over summer, algae took off. Also, I am on Team...

There's clearance for tubing and the clamps on both hose barbs in that screw area? That right one also looks right against the side with a hole in it, too. Annoyance ahead.

What is your beauty below left of your torch, above those rock flower nems? Elegance? I admired it since your first photo.
