So we have a 16 gallon tank that is in the process of being upgraded to a 55 that is a rock nem garden. Currently only has 2 maroon clowns a bunch of rock nems and the usual cleaning crew? We are thinking about adding a dwarf lion as the sole fish inhabitant but I can’t seem to find any compatibility info on the lion and the rock nems. I know he will eventually be big enough to turn the maroons into a midnight snack but I am planning on re locating them to alternative housing. Will a lion be ok with the rock nems or should we seek other inhabitants.
