So, I've been perusing Craigslist. Seems like there are a ton of deals on 100+ gal tanks.
I want to do freshwater, though. I want Dwarf Hairgrass to cover the bottom. I love the way it looks when it's all over. So lush and green.
And then I'm going to just put a bunch of schools of peaceful, non-aggressive fish in there, like Neon Tetras, mollies, danios, killfish, a betta, discus, fancy guppies, gouramis, and swordtails. I've had cichlids before in the same tank with barbs, and they did okay. So, with such a large tank, I might be able to get away with one or two, but if I do, they'll come dead last.
What kind of filtration system should I go with? And heater? I've been reading that I should probably stay away from an undergravel filter because of the size of the tank.
Does that sound like a good plan?
