I check out the photo galleries on this site and all the axies seem to be slim and sexy with gorgeous great fluffy, frilly gills. I accidentally adopted an axolotl a few weeks ago, being otherwise a complete newbie to this. He is (a) obese and (b) has funny stubby short little gills. He was previously being fed on lamb liver every other day but I've put him on a diet of one earthworm twice a week. It doesn't seem to have had much effect so far (from above his body still looks twice the width of his head). As for the gills, their lack of frills doesn't seem to bother him at all - he's not gulping air or anything and is quite happy to stay submerged. As far as I can tell he seems happy enough - he's certainly pretty keen on his meals. I got him in a bare tank but he now has a fine sand substrate, a cave (he likes that), assorted rocks and plants, and a proper filter. Any advice on the weight-loss diet or the gills?
