What size tank do you have?
Any tank mates?
I keep mine at 76 degrees. Like you I bought it very small. It has a metabolism like nothing ive seen, it can easily eat every hour. I don't feed that often though. Its been in as small as a 30 gallon. As it grows I've re homed it though. Honestly I've only been able to get mine to eat live food. For instance lizards, crayfish, and yes the dreaded goldfish. There are methods online to introduce the fish to pellets none have been successful for me. While small mine hid a great deal, now its probably right at 6 inches so it never hides, it would rather demand food lol. My peacock is no where near the size it will be though. Please let me know if you fine other foods for it.
