I have heard and read that curled gills mean an axolotl is sick or stressed. Can you tell me if Chester's gills look ok? I cycled my tank, the bubbler is on low and the filter is turned very low. He is eating well, if fact he seems to have eaten almost all the ghost shrimp I brought home today. He has been getting blood worms but I have worms coming from Uncle Jim's Worm farm because I think he will be able to handle them now. So, how does he look?
