To add to the previous advice, i would very highly recommend using live plants...in LARGE quantities. Also, do small water changes regularly...it´s difficult to tell if your water is high in tannins or simply filthy.
Obviously i assume you weren´t hoping for this kind of response, but your current set-up is really not adequate as it is. Check the CC articles (links in signature) and make the necessary changes. These are very easy to care for newts and very rewarding when housed properly. They can give you joy for many, many years if you treat them well.
My axie is acting woerd he was a rescue as stated in a different post he got better and now seems to be deteriorating again...again all tank conditions are OK and as should be. He seems to have some black dapple like pattern under his bottom lip? Is that normal? And his two back feet have a little wierd growth? Almost? Tiny tiny tiny lump. His capillaries in his feathers also appear darker and more visible. Any help would be appreciated
