I have 2 predominantly tetra tanks, one African, and one South American , and all are doing well, but there is always an urge to do better… I do feed some frozen foods, and I have noticed, that the very small palmeri’s and rummy’s have to pick and choose small pieces out of the brine shrimp cubes, same for the African’s, both tanks have other fish that will eat the bigger pieces (dwarf cichlids, and angels in the South American tank, and the 3 lined glass cats in the African tank) … I’m really pressed for time, so the “easiest” part of the title is important… I do have a brine shrimp hatchery, that I bought a while back, that I haven’t had the time to get going yet… so baby brine shrimp… anything else that would be easy, not time consuming, and would be palatable to small fish???
