I've got 9 zebra danios in a 20 gallon tall (footprint 24x12), lots of nooks and crannies with rocks and fake plants, with excellent filtration and would like to add a little more color and maybe some bigger fish; what are some recommendations for good tankmates?
I've been thinking about dwarf cichlids - a local fish store has keyholes (probably my preference), apisto borellii, and rams in stock (I really don't want rams because I've heard they can be delicate and more aggressive). The aquarium temperature is quite warm - around 80-82 degrees - because I have no control over the room temperature. pH is slightly above neutral.
