I just picked up a couple spotted Raphael cats - one was noticibly bigger than the other (no longer - just wider middle and bigger head lol) and instead of having white spots on the belly has orange ones. Its it a variant/just happens this way/ a different specie maybe? Just curious never kept these little guys until recently. Awesome little fish, makes me wanna build/acquire a big tank for a couple of the big niger species that are popular.
