For those of you who have had either of these animals as long term captives, have you noticed dorsal or ventral changes in colors, spot shapes or patterns as the animal ages? I have observed this and made comments to this effect on various discussions in this forum yet I haven't noticed other keepers either refuting or substantiating this observation. So, I thought it would be worthwhile to hear from the community.

For ecological studies, pattern matching methods are getting increased attention as a means of tracking and identifying animals as a less invasive method. It is being discussed here: http://www.caudata.org/forum/f1173-...toma-year-plus-belly-patterns.html#post419347

As long term keepers, we are uniquely positioned to observe changes where field researchers may not have this advantage. Please share your experiences and if you have pictures that you can post, it would be much appreciated.
Thanks
Jan

    Hello. I’m looking for some input. My axolotl is about 7 months old. I came home and her gills are completely white. I was reading that they do shed around this age. Could this be why her gills are white? The ph is 6.5-7. Nitrates are 80 Nitrites 0.5

    My axolotl’s gills have turned completely white. she is about 7 months old. I fed her a couple of pellets to see if she would eat. One hit her head and she flipped out. Started darting all around the tank. Temp, ammonia, nitrates are all in range. Anyone know why this is happening? I pu

    I believe my axolotl is constipated. I got him 8 days ago and have not seen any poop in his tank. I have a 20 gallon tank. No other tank mates. 2 hides and a bare bottom. I didn't feed him the last two days. His belly looks swollen and dark in color. I believe it is the food you can see. I fed him blood worms and soft quick sinking axoloty pellets. I tested his water today. Ph was 7.6. The nitrite and nitrate were both zero. The ammonia was 0.25 ppm. I was advised to cycle my tank due to the lack of nitrate. I added Seachem stability 10 ml to my tank yesterday and 5 ml today. I have a tank chiller. The water temp is set at 64. He is still active, but his tail floats up when he is moving about the tank. I am on the fence about fridging him. I also don't know how long to go without feeding him. I don't want to harm him. Please help asap. Thank you.
