a friend of mine has a 20 high with a magnum hot canister filter and he wants to know if it would be too much flow for his tank for the fish he is going to be getting.
He said he is going to get one betta, a couple platys, 2 three spot gouramis, and 2 pearl gouramis. Do they make any H.O.T magnum canisters that don't have a powerful flow?*twirlysmi
There are many HOB filters available for 20g tanks, if he wants to buy a new filter.
You should let your friend know that bettas and gouramis don't make good tankmates. Three spot gouramis will most likely kill the betta and the other gouramis (including other three spot gouramis).
thanks lotus i will tell my friend that he cant have gouramis with his betta and will tell him to get a hob canister for a 20 gallon. thanks again*twirlysmi
if you go to petsmart or whatever LFS, there are plenty of hang on back filters for 20 gal tanks. it says on the package what size tank it would be best for
