I picked up a free 20g + fish earlier this week. There's a 3-4" angel, a 6" pleco, a little bristlenose pleco, and this guy:
The previous owner said he was a discus, but he doesn't resemble any discus I've seen. Granted my experience with them is very, very limited, but I've not seen one like this. Anyone care to ID him? Is he ok with the warm temps and soft, acidic water that the angel needs? They don't fight.
