thanks now one other question I have that isnt really related..

One of the robbianus have what looks like a ctaract in his/her eye. Doestn seem to bother the fish at all but any idea if it is a fungus or something natural?

but when I do a web search on the species they say it is it shows a different syno.. anyone got any ideas?

By the way I have had the fish for about 2 years now and he is the angriest fish in the tank to anyone in the bottom of the tank.

2 s. robbianus ...
