Hey guys, I'm putting together my first planted tank and designing it around a Rainbow species. All of them actually. But I still need the ones who will take care of the tank. Shrimp are out as Rainbows will eat them with in a few minutes ( I know this the hard way). I think snails will do ok, but I need fish. Golden Algae eaters and Otos are a likely candidate. But I am here for your info. So what do I need to keep a moderatly to fairly heavy 180 gallon tank with low/medium T-5 lighting clean? And as for that, how do I figure out my fert amounts and schedules?
