the species are: acei, jewel, red zebra, bumble bee and demasoni. they are not bite sized, infact they are all almost full grown with the exception of the bumblebee because he grows much larger than the others. they are all roughly 4 - 4.5 inches.
Yes, it would be fine. As long as it is not worm sized and tempting itself. I have 3 senegals (9", 2 at 5") and an ornate with my americans. No problems.
yeah it should be fine, my boyfriend has one in his cichlid tank and all he ate were the danios up top, he'll only eat what fits in his mouth, doesn't really bite persay
