Should I get another adult?

[Nova]

Hi all, I'm just looking for some advice/ opinions again! A couple of weeks ago one of our females had to be put down after developing kidney failure/ septicaemia. She was isolated as soon as any signs of illness developed and the remaining female has shown no signs of any illness whatsoever.

Since the ill girl was removed the remaining girl (Trevor, don't ask) has been noticeably sulking. I swear I'm not anthropomorphising here. She was always a bubbly active little creature now she mopes a lot. She follows us round her tank constantly. I had never really considered whether axolotls are social animals but I'm starting to wonder if getting her a new tank mate might be a good idea.

2 issues here - We have had Trevor for 2 years and she was fully grown when we rescued her. She is HUGE. Properly big. This means we might have trouble sourcing a large enough tank mate to go in with her, ideally I wouldn't mind getting a male.

Secondly the tank is 100L, do you think it is big enough to add another adult too? The two of them seemed very happy in it before but if you think it would be cramped then I will just leave her by herself. Many thanks for any responses!

Edit: Posted this in the set up section as I suppose really the main question is can you comfortably house 2 large adults in a 100L tank

First thing to consider is that being very active is not what i would call the natural behaviour of an axolotl. Of course there´s variation between individuals, but inactivity and "sulkinness" is pretty much what axolotls do. The following you around when you move near the tank is not that it is asking for attention or company, but rather that it thinks there may be food coming.
It´s up to you if you want to get another animal, but personally i think a 100l tank is adequate for a single large adult, not two (i know there are dissenting opinions). If you decide to get another, i would wait a reasonable amount of time.

They really are not social at all. At best they tolerate each other.

I agree I do think it would be pushing it to add another. Although I have seen smaller tanks with more than one in It looks cramped to me. Hmm. Will think on this one. I was to keep her by herself for a couple of months anyway to make doubly sure she doesn't develop whatever the other female had. Perhaps if after that we still want another we will look at getting a bigger tank. Thanks for the reply.
