I have 2 tanks-one is 33 Gallons, the other is 10 gallons-I have a bowl but its only for moving fish around or keeping the betta in when I clean out a tank (he doesn't do well in cramped quarters). in the 2 tanks there's; in the 33 gallon -Amoeba Jacket – Comet -Montreal Waters – Comet -Phil Collins – Shubunkin (I think its a Comet)* -Lenin – Shubunkin (I think its a Comet)* -Biggie Smalls – Comet -Lt. Orange – Comet -Nightfish – Betta -Hercules-Comet -Mercury-Comet * they were labeled as Shubunkins when I bought them about 2-3 years ago its a tank full of neatly coloured fish, and varying sizes too. In the 10 gallon; -Dennis Genesis – Comet -Fatty-Mosquito Fish -Donny – Mosquito Fish -Dave Hugo – Mosquito Fish Originally the Betta was in the 10 gallon but he didn't get along with the little Mosquito fish, so he went in the big one and I put a Comet in the tank with the Mosquito fish and everything is fine, if I get another tank i will probably get another Betta
