Loaches Online Forum

I have clown loaches. The fish guys didn't know what it was, but I tried the copper. The loaches seem to be much more lively. I was wondering.....I usually use reverse osmosis water for my loaches as the water from the tap, where I live is very hard. Do you think I need to add minerals to this water...

I have noticed some black spots on my loaches...mostlly around mouth, but some on the body as well. These spots are quite small. The fish guys said to use cupramine half dose. Does this sound OK? What do you think it is?

Thanks

Karen
