Don't know if it was the angle or what, but is your tank a 6ft or 8ft? Either way nice so see him have so much room.
My Toni is in a 6ft 125. She has now 11 Silver Dollar's and a p. Ornatus catfish named Catness Everwisker as tankmates.
It's to bad she had to go and eat one of the Roseline sharks they were great tank cleaners. No fear these guys, they would hover just behind and below her to eat all the gill leavins she spits out while eating. The SDs do some cleaning up, but not as intensely as the Roselines.
