Hi all currently I have a 125 gallon tank (I know way to small) with a starry night, frontosa, 3 BPs under 4 inches, a small female convict, an Endlicheri bichir, a tire track eel both at I'd say 10 inches, an ornate bichir around 6 inches, last but not least my oscar at 10ish inches. I know this tank is way too small for all those fish, however It has been doing well with really no issues, but anyways I am planning on getting a bigger custom tank this coming summer when I have the funds to do so. If my floors can handle it I want to get a decent size tank to fit all my current fish, something around 300 gallons. If anyone has any good ideas on size and,or dimensions of a tank for these please let me know. Thanks!
