Feeding red tail catfish?

  • We are currently upgrading MFK. thanks! -neo
Crusteceans are a big part of RTC diet in the wild. So, yes, frozen-thawed is fine. But do not make it a staple, always give other foods and more of them than say shrimp, which is high in thiaminase: http://www.theaquariumwiki.com/Thiaminase
 
Catfish pellets (not necessarily the most expensive but not aways the least expensive; mixing them is good) plus pieces of fish/whole fish, frozen-thawed. I used to buy 25 lbs of marine fish called spot for $15-$20 from a small local food fish shop. Mix different pellets and different aquatic/sea foods in every now and then.
