FUCK. THAT. lol
I'll stick to 50 goldfish in a 10 foot tank lol
Mate, just get yourself a good filter and heater and you can get some really beautiful tropicals.
Neon Tetras are like a discoball for your tank, but man they get eaten fast by Angelfish.
If you are after weirdness, get Plecos or a black ghost knife fish, just make sure the parameters are good and also make sure that you dont have sharp rocks or ornaments. (only coz the knife fish have no scales, but slime instead)
If you're after just goldis, get the bubblehead goldis, they are precious fish with terrible breeding, so i kinda feel sorry for them kept in captivity.
