PineSong Posted June 6, 2021 Share Posted June 6, 2021 My previous tanks have been single-species: either all goldfish or all platies or single bettas. In planning my new planted tank, I'm trying to think more along community lines--probably platies and a gourami, maybe a few guppies, and a snail or two. My question is whether there's such an advantage to having bottom dwellers like corydoras or kuhli loaches that a planted tank should pretty much definitely include them as a maintenance crew, or whether they are more of a "good to have if you like them" fish. With only 20 gallons to work with, I'm reluctant to give bioload space to fish I'm not super into. Cories are cute but the fact that you need 6+ is significant in such a small tank. Thanks for weighing in. Link to comment Share on other sites More sharing options...
