Filtration and lighting for threadfin rainbows?
I am starting up a low-tech planted tank for the first time. The tank is a 40g breeder (36x18x17" tall). My plans for the tank are to feature threadfin rainbowfish in a heavily planted tank. I have never kept these fish before so I am learning both about the fish requirements and the plant requirements. As far as filtration, I have read that threadfins come from swamps and backwaters with slow moving water, so I was wondering what would be a gph rate for a tank like this (i am planning on using a canister filter). The eheim 2217 is 264 gph (too high?) while the 2215 only has 164 (too low?). The concern I have is keeping a good oxygen level but not blowing the delicate fish all over the tank. Does any one have experience with these little guys?
Also, I am thinking about running cfl lighting over the tank. This lighting is new to me (I am used to saltwater lighting). What would be a good wattage to start with and how many bulbs (thinking 2-3) but more may be needed.
