lol, hope my 30 loaches of 20 different species dont read that article. Though i do disagree with the aggression issue, my cichlids dont even pay them any attention. Tho, i do have mainly open water haps and A LOT of loaches. I must admit im not planning on keeping them in hard water long term and i am going to set up a loach tank better suited to their needs. BUT, for the passed 3 years i have kept loaches in my malawi tank, KH 8 to 10, pH 7.9 to 8.1, and raised them on New Era African cichlid pellets aswell as frozen mysis shrimp, brineshrimp with garlic and tubifex. And they are in fantastic condition. Beautiful body shape and happy as a happy loach can be. Some are even hand tame now and actually come up to feed out of my hand when they think frozen food is on offer.
I think im developing an addiction to loaches!
