Thank you all for the advice! Didn't expect this many replies!
I'm pretty dead set on a tank size in the range of 10-20g due to limited space, but not on the model! I like the sleek look of the Innovative Marine Fusion 15 tank and I see it's about 3 times cheaper than the bio cube. Is that just because it doesn't come with lighting? If I would need to get my own lighting, what would be a good light to fit with it?
My takeaway here is that I need to lower the number of fish in the tank. It's very important to me that the fish are given a good home, so thank you for letting me know! I was watching some videos yesterday and saw an alternative to the blue tang was the Yellow Tail Damsel. I'll take a look at the fish lists you all provided and try to curate a new list
Also another question - Should clown fish be bought in pairs? And will they fight if they aren't the same exact species? I'm seeing mixed information online
They can be bought in pairs but they don't have to be. Definitely don't mix species they will kill each other. The risk with buying clowns that aren’t already paired is they may not get a long (maybe kill each other) or it may be love at first sight. If you go that route be ready to separate them if they don't get along. It also helps if one is much smaller than the other one.
I would encourage you not to consider maroon clownfish, or clarkis for the reason they are highly agressive and they get larger than other types of clownfish to big for your intended tank size.
If you are patient you can find a deal on a really nice pair of fancy clowns many people in the bay area breed them if you want something different than standard
orange nemos.
I have a bio cube there are lots of potential hidden costs to them as in you will want several upgrades to them as you learn more about the hobby (I've probably spent upwards of $350 on add ons to mine, light bars, media basket, in tank refuge, uv sterilizer just to name a few. They aren't required but as mentioned you most likely eventually want some of them), so the tank the others are recomending even though Doesn’t include a light may actually be cheaper all things considered.
