Come on guy HITH is caused by FEEDERS that's what the paper said in the begging of this post so now your saying you think it's the water quality? Ok so then feeder's are safe then and good and nutritious for our fish's? The only other argument I have heard here is it makes your fish fat. THAT"S why we are promoting feeders we want to put the fat on our Cichla in the first year. I am in no way saying feed exclusivly feeders forever. In the wild they would have an endless supply of feeders healthy and unhealthy they still eat them. So what is your argument again? Are feeders a good source of nutrition or not? Or do I have to wait until you write a formal paper on the subject?
