Hello i have two juvenile axolotls and i think one of them is sick, He seems kinda sluggish but he still eats, I have a wild type which is gotten pretty big so far and is doing really well and the sick one is a golden albino. im a new owner to axolotls but i make sure i do 100% water changes on the golden albino because he is in a 10 gallon tank right now because he is still so small. I do daily ammonia checks and the other water tests to make sure everything is safe here are some pictures of him please help.
