This is my new little leo, It's a girl and i think she's a Tremper but im not sure if anyone knows what she is please tell. Tell me what you think of her.
Sweet bell albino and yes housing them together is bad. The banded one is merely a baby still your new leo is a juvenile. The poor baby will get pushed over. This can cause stress to the leo and on babies specially this can be fatal.
Also, you should always quarantine a new gecko, even if it's coming from a reputable breeder. You never know if the new gecko is carrying parasite or worms. House in a seperate cage as far as reasonably possible. Have a fecal done. Some people say 30 days is good for quarantining but I preffer 60-90 days. At the end of the quarantine period have another fecal done. They (worms/parasite) won't necessarily show up the first time around.
Nice Bell Albino. What's the sex of the gecko's that you own?
There's not much that you can do until you get a separate cage. A partition will keep them separated BUT, if either one is carrying something the damage is already done.
Right now you won't know which poop belongs to what gecko (unless you see them do it), so you'd have to have every fecal checked.
P.S. On you website you have a "collection" page. Check your spelling.
