i have a 60 gallon tank with 3 columbian tetras and 2 dwarf gourami my ph is 7-8
My water Ph is 6.5-8.5 the hardness is 3 for my tap water I use api tap water conditioner and a marine land filter and a 60 gallon heater
it is the the space because gouramis are in the same family tree as Betas so they will claim a territory and fight till either one dies or goes to another home but since your tank is to small your going to Have to get a bigger tank of 30 gallons or more and put many hiding places in the tank so...
Is there any chance I can just shrink these amount of fishes because the cost is $88
12 Cory cat fish-$37.08
8-10 skirt tetras-$16.27
10-12 rosy barb or tiger barb half female/male-$27.9
