Over the last month I noticed that my 2 foot L. pictus started to regurgitate food. At first it was the Massivore pellets so I thought that was the case. I did a water change, Put in an additional submersible filter and water quality is as follows. Almost no ammonia, .25 nitrate, 6.5 ph between 82-87 degrees-its summer in Miami. He always seems to do this when i show up in the morning to say hello or feed them. I was feeding daily but then reduced to every other day. how often do you guys feed your bigger cats. Smaller TSN 14" and Lima 8-9" pleco oscar and Tinfiol barbs all seem cool. He even started throwing up market shrimp. It has happened 4-5 times that I noticed. any help is appreciated.
