I have a group of seven of the habrosus cories, right now. They are a nice little fish, more outgoing than my pygmaeus cories. This is actually my second group of habrosus. The first group of 10 died off one by one till I only had one left. I still have that one. They would sit on the bottom with their dorsal fin clamped, and then they would die.
This new group of six (plus the old remaining one make 7) started to look sicky just like the first group. I decided to treat them first with a full course of General Cure, then with levamisole, and then with a full course of Maracyn and MaracynII. They all look great today, and I've had them for about two months.
I hope yours do well for you. They are so cute. Mine like tetratab pellets, shrimps pellets, and frozen baby brine shrimp.
