No worries about the questions; I would like to know what if anything I have done wrong.
My tank wasn't cycled (I know, I know - with my research I read that I could do a water change every day. Won't be repeating this again as I now know with my fish just how important it is to do a proper cycle. My fish are still alive so I am hoping/assuming that I am monitoring their tank correctly). I did use dechlorinator. The water test that the pet shop did indicated no chlorine, ammonia, nitrate, nitrites, and the kH and gH were okay as well (I think those last two are the correct terms?).
It did eat a tiny bit of meat. It was a tiny flake of meat as the axolotl was only 4 - 5cm long. There was more meat in the tank which I removed that afternoon as I didn't want it to decay and cause problems. It ate the day I came home to find it on it's back which made me think it could have been obstructed, but honestly can't think how an obstruction could occur after such a small amount of food.
The water was fresh into the tank on the same day the axolotl came home.
The tank is roughly 54l. Measurements are ~600 wide x ~300 deep x ~450 high.
It may have been an outside toxin, but as my other fish tank is in the same room and they are all fine I am not sure what it could have been, and none of the cats are allowed in my room. The only things I can think of that may have been the culprit was a big piece of driftwood that I put in its tank, but I bought this from the aquarium shop, or the pebbles which I bought from the Warehouse. Everything was rinsed of course before I put it in the tank but maybe there was something there that killed the poor little thing.
A glow in the dark axolotl?! Haha what will they think of next?!
Thank you all for your replies so far,
Amy
