About now, 4 weeks ago I rescued a snowfick eel from a local farm supply pet store. They had them for a year in a 5 gallon tank.it's nasty on the bottom we bought him brought him home right now. The worker will just throw krill in the tank. He's gonna little bit bigger tank. But he is not eating from the tongues. What do I need to do I want to put him in my 300 gallon tank with my other snowflake eel but I do not want to until I know he is eating.
