Hi,
Almost 2 decades ago (I'm getting old

), I bought two large loaches that were over 30cm long from a local pet store. They would only eat live earthworms that I had to buy from a local bait store. Fresh out of college, I couldn't afford this for long and tried giving them various other foods such as frozen/dried shrimp, shrimp pellets, etc. They simply refused to eat them and I had to constantly take the food out for fear they would foul the water. They didn't last long

. I have since been quite successful keeping and even breeding cichlids. I still dream of stumbling into some large ones.
So, my question for those of you that have large ones (over 25cm long), what do you feed them?
Thank you very much for your help!
