WE NEED PICS! So glad you found one after so long! Sounds like it is still young. Mine eat anything and everything made of meat. Mine stayed on a diet of worms and jumbo shrimp for a long time. Then kinda got annoyed by the $3.25 for 2 dozen worms which doesn't hold out for very long. Figure we could get fancier if I was going to spend that much on food, when one can easily take a dozen worms in a week. Now as adult I buy fish from the supermarket. Frozen or fresh. What ever works for you. Mine have eaten catfish, talapia, smelt, haddock, salmon, and shrimp. That I can remember. Just cut it up into long thin strips and they have no problem eating it. Treats are whatever I throw in the tank usually something not considered "healthy". Cooked chicken, beef, pork, calamari, cheese. They happily eat it all. The younger they are the more likely they are to eat things, they seem to have a higher food drive. Once mine ate some sauteed mushrooms when they were little
. They would probably be too lazy to eat something like that currently. They use to tear apart worms, but now the fat adults are very particular on their worms. They need to be torn in half cuz they will only eat them from the injured end.
I suggest starting to feed when the lights are out it is more likely to eat a good meal that way. They vary in character. My male has little problem eating during the day or with being gently handled. Female definitely prefers the night and freaks out pretty easy.
Make sure your lid is tight with no gaps, they are expert escapers.
