Does anyone know any type of fish that can live in a 2.5 gallon sw tank? I have one set up that I want to keep in my classroom, but I'm not sure what I can put in it. I kind of wanted something colorful for the kids.
2.5 is quite small for a SW tank, and a bit tough to keep your water chems stable. I'm no saltie expert but I think making this tank saltie will be limited to a shimp or two.
bunch of tube worms in there and some corals maybe a few sexy shrimp and if you hook up a sump to add gallonage and filter power a clown goby or neon goby.
but i think inverts are best, and honestly if you do them right they look pretty good too.
Looks like you have some aptasia anemones. peppermint shrimp woul be a good candiate to clean those up! When I had one, it ate the aptasia overnight. You have to keep the water nearly pristine.
