thanks for all the sugestion. i thimk i will go with the pictus or clown loach. and one more question, are pictus social? i was intending to only get 1.

I have mine in groups of 2. But the woman I got them from had all 4 together. Hope this helps.

i have mine in a group of three but i know others who have succefully kept single specimens

I have 2 and the only time they have contact is when one is chasing the other. I read somewhere that the older they get the more they want to be alone.
