I use a pair of empty HOB filters + an activated carbon reactor on a 10gal tank - no cloth, floss, rocks, rings, sand - nothing that a parasite can lay eggs on.
fleshy im a bit confused on the reasoning behind the fact that a blue hippo would be fine in this tank for life but a harlequin tusk would not, if anything the tang swims more than the tusk and gets longer. just legitimately curious as to yours thoughts on that
Marine Betta - 5" maybe (from mouth to end of tail fin)
Pencil Urchin
Sand sifting Starfish
6 Green Chromis (small 3/4" - 1" each)
Banded Shrimp - big boy
**All of the above came with the tank when moved to my house**
Additions since moved
Blue Hippo - 4"
Maroon Clown - 3-4" (big chubby fat guy, lol)
Copperbanded Butterfly - 3-4"
(3) Bartlett's Anthias - about 3" each
The HFIC (Head Fish In Charge) is clearly the Hippo with the clown not far behind. Everyone seems to get along fine so far although the clown did not care for the copperband for about the first 24 hours or so but things seemed a little better yesterday evening.
We are done with the tank for a while as I don't want to go too fast with adding fish (that and the fish budget is shot for the next several months). We are pretty happy with the way things look and the addition of the copperband and anthias this w/e has given us a lot more movement in the tank. Also the copperband has already starting working on the aiptasia in the tank so that's a win there.
13 fish and 4 large inverts in 1 month in 125gal minus 1/3rd for rock displacement isn't what I'd call going slow - good luck with that your gonna need it.
