Starting out

gearish · 2026-09-23T17:10:31-0400

I really want to get into reef tanks and I’m already doing the most research I can. But looking for some opinions. I want to start out with a 20-15g cube AIO, but I wanted to know if these would be good beginner specs and when adding a fish, could smaller species of clownfish and some CUC be ok with that size. And I’m looking for some other insight on stuff like lighting recs for the tank and some other tips. Anything helps :)

Yes, a couple of clowns is doable. Good luck and welcome, glad you are here!
