My male and female RES have been sharing the same tank for about 13 years now. I took them in from my brother last year and upgraded them to a tank about twice the size and they seemed to love life. But shortly after, the male (Tex) began to take chomps at the female (Rex). It didn't happen too often, but this past week it has almost been constant where I am forced to intervene and Rex even got a little chunk of her tail bitten off
2 questions - are Tex and Rex just sick of each other and I need to separate? Tex has not been eating lately (we're talking weeks here) but I just tried the hard boiled egg tonight and he couldn't eat enough of it! I thought maybe he wasn't happy with his diet and taking it out on Rex...
Secondly, now Rex has the little bitty piece of her tail dangling. Should I apply any ointment? I don't want it to get infected. Will it fall off, regrow? It's a pretty small tip that got chomped.
Tank info:
45 gal
Water temp 75F
Basking temp - don't know, 90F?
Usual diet is pellets but they won't eat those anymore as of 8 weeks ago
Any advice greatly appreciated!
