I would like to have some kind of catfish in my bichir tank. I have read the synos may suck the slime coat. I have a couple in another tank. One is a feather fin, one is an ocellifer and I'm not sure of the other one. Would any of these work? How commen is it for synos to suck slimecoat? Lastly any suggestions would be great! I would like them to max out at around 10-12" if you have any ideas.
