Axolotl size

[roeanddarwin]

hi, i have two axolotls called roe (leucistic) and darwin (wild type). since i got them in december, they haven't really grown much. i'm doing everything i can, feeding them correctly, the tank is big enough and it's the right temperature. roe is about 7-8 months old and darwin is 8-9, maybe 10 months. i am quite concerned for my axies. thanks

:happy:

What are the parameters - ammonia, nitrite, nitrate and PH and temperature? What are you feeding?
