I figured out that pictus cant breed. So i got this from fishfourms.com, And a guy on there has the same issuse, a few people on there said that it either ate to much or is consaparded. so I'll wait a few days to see what happens.
I wouldn't put anymore fish in this tank. Wait until you upgrade to the 55. Did you cycle the tank? What are your ammonia, nitrite, and nitrate levels?
