Yikes....
I have alot of fish in my 37 tall tank and my 10....
In the 37 I have 1 parrot cichlid, 1 festivum, 4 black neon tertras, 2 big black skirt tetras, 4 rosy barbs, 2 weatherloaches, 2 clown loaches, 3 plecs, 1 dwarf gourami, about 3 otocinclus, and one very mean looking jewel cichlid.
In the ten there is tons of home bred guppies (I estimate around 40), one male betta, a green corydoras, two home bred sailfin mollies, and a home bred swordtail.
In my 77 I have a pair of breeding oscars, a massive unknown catfish, a large plec, a blue acara, a jack dempsey, a tinfoil barb, and a red devil.
In my 55 marine I have 1 small chestnut moray, a green chromis, a lemon damsel, a blue devil, a red hawkfish, and a sebae clown, plus tons of large and small invertebrates.
In my 33 I have four silver dollars, (2 small, 2 large) a spotted pictus, 3 giant danios, and 2 larger chestnut morays.
People would say this is over stocked, but Ive had it this way for a very long time.
