I purchased a 7.5 inch tt eel and a 5 .5 inch peacock eel. i got both eels about a month ago and have been offering them flakes, shrimp pellets and various other dried food, to include freeze dried krill. they would not take these but i guess they were eating something after the lights went out. they rarely even came out of their hiding places. today, i throw in a cup of frozen blood worms. they both came out and went into a feeding frenzy. i'm happy now, because i now kinow for sure, that they are eating and will flourish and survive in my tank.
