I bought an rtc with gill curl a while back and didn't really notice until recently. Does it affect the fish's health. It seems like it doesn't but i dont know for sure. It doesn't seem to because the fish eats like a pig and actually goes after the large goldfish feeders instead of just waiting for the fish to pass by like the tiger shovelnose. Anyways i wanted to know if it is a sign that the fish is about to die or what but i had it for a while and it seems ok. when i got it, it had gill curl but at the time i didnt really know what that was so can anyone help?
