Hi MFK members.I have been lurking here awhile now,learning that I should have been better informed before buying.At the time I had a 72 and a 90 gal. tank.I purchased 2 fire eels the size of a big night crawler 1 for each tank.I was never informed how big they whould get surprise! Presently I have upgraded to a 125 and a 180 gal.tanks.Best I can do for now on buget and size of my house.Anyway it has been almost 2 years now Sparky who lives in the 180 must be 28 inches and almost as big as my wrist,Einstein who lives in the 125 30+ inches.I started out feeding blood worms out off turkey baster till they got bigger then onto worms,then worms,shrinp and Home made discus food.After a while they seem to get really turned off by the shrimp and BH mix.I do not know how to describe but they just did not seem right after eating shrimp or BH.Anyway my question is what else could I try feeding them and how much to feed them?I searched forum quite a lot and mostly found people asking about small eels.Hope this is alright I have never typed before 1 finger wonder.Thank you for taking time to read. Hope someday I can help someone also.Sorry I forgot to mention they absolutely will not eat fish live with neons and white couds and zebras never bothered them once.also tried Talapia no dice.THanks again.
