Hypsophrys nicaraguensis

[croc 2-3]

Angels can deal with geos, and Nics. The reason I know that is because I had them all in the same tank for about 4-5 months. I recently lost my geo and my angel, so the male nic is the largest in the tank at about 5-6".

I'd remove the jags. or they will remove most of your other fish soon especially if they are bigger then 5 inches. 1 jag alone will probally be enough for the 55. get 2 more tanks to split the fish up once they get bigger but get the jags out now. The rest of the list will be fine together.
