I have a 120 gallon tank (4ft x 2ft x 2ft) with dual overflows. I want to set up a planted tank and I'm looking for ideas. I have two 48" Finnex Stingray 2 lights. I'm not sure if I want to set up a sump (a first for me) or use the canister filters I already have. I need to select substrate, plants, and fish.
I'm returning to the hobby after a 10 year break. Before that, I kept fish for 15 years and I'm looking forward to getting a tank started again.
What I'd like to do is get a large school of rummynose tetras (with other "supporting cast" fish) and low maintenance plants and maybe a "centerpiece" fish. Possible ideas for other tankmates: kuhli loaches, cory cats, ottos, hillstream loaches, inverts. As far as substrate or plants, I'm suffering from analysis paralysis.
I would love to hear ideas/suggestions/warnings for my proposed setup.
