Floating Lethargic Axolotl

[milkandchips]

Hi I am a new member here at caudata, i currently own 2 axolotls, named milk (leucistic) and chips (melanoid). They are kept in a 30 gallon tank with weekly water changes and a 980L/H hang-on filter.

Milk is kind of sick? He/She (I've never been great and differentiating animal genders unless theyre very obvious) has been lethargically floating at the top and refusing faborite meals such as bloodworms. They are still juveniles (if I'm not mistaken) and are somehow unable to 'vacuum' the earthworms (cut up) i feed them. I sometimes rotate to hikari sinking carnivore pellets. Milk very much prefers blood worms and used to have a big apetite. Recently it stopped moving altogether and doesnt even try to get to the bottom of the tank. The water conditions are fine except the pH level being a little bit low. The temperature is also cold enough for them. Weird thing is, their discharge colour is white ? Like aquarium stones and they havent been pooping right for some time now. I dont use any kind of substrate and have no small decorations that can fit in their mouths. Milk swims around the top area and sometimes try to swim down but fails halfway and floats again.

Should i fridge Milk? Or what am I supposed to do?

I have read of floating axolotls over and over. I'd do a search on the forum and see what comes up. GOod luck.
