kindabeaslbob, you put macro algae in your tank to get it cycling?
Good luck getting it out lol. Alot of people plan on moving fish when they get too big or aggressive , ect. Much easier said than done. It looks to be a yellow tail, so your lucky in that way
I think it's interesting how a yellow tang eats the chaeto. Kinda slurp in in. LOLYes if u use macros they need light.I keep mine in the display and it works good too. Except in the tank w my fox and yellow tang. Wont eat cheato my ass lol
