So I've had my RTC since 25th of last month.. so not that long. I did a lot of research and tried feeding him every 12 hours with 2 very small pieces of tilapia. He was eating perfectly fine until Friday the 31st. He started to vomit any food i fed him. Since then he hasn't ate at all. I've done a water change, ph levels are 7.2, i have plenty of places for him to hide. Im just not sure what else i can do to ensure his well being. *ADDITIONAL INFO* First was placed in a 10 gallon for 2-3 days then transferred him into a 55 gallon. (Ate perfectly fine in both) He still is about 2-3 inches. Thank you again if you read this
