Yeah ive heard they have to live in shoals or theyll "die from loneliness"... I dont mind getting 4 or 5 though; they are interesting and different looking fish and thats what im going for.
Although I love the color of the dwarf neon blue rainbow fish, I dont think they would last too long in my tank since they only get up to 2" and the bichir will most likely eat them. So Im looking for other suggestions. Id like something colorful b.c currently all the fish i plan on getting are clear, brown, gray or black.
