WORRIED My milk frog has what looks like a blister

[flybyferns]

Hello again Ashley,
Yes, you are right; you have a good reason to worry. Your milk frog needs vet asap.

This is one, very, odd looking blister ! The color confuses me.
It could be a foreign body ? ( splinter) are there any fake plants in the enclosure?
This little guy could have been bitten by one of the anoles

I have a few questions:
Burn ? are there any 'heat elements' he could have been near?
Did you apply any medication?
Have you found / had any kind of insect the tank?
What do you feed the anoles?
Do you see anything moving around under the skin ( in the blister)?

He needs to be moved into a sterilized hospital/enclosure.
Do not break the blister, let the vet do it.
He will need a topical or systemic antibiotic.

We really want to help you. Soooo, I will be as blunt as possible.
Every species you are housing in your enclosure should be separated!
It as simple as that…… NO matter who told you otherwise!
I know it's a large tank, but unfortunately that does not solve the problems that will continue to occur , especially for the frogs.
Sadly, sometimes you can get really bad advice. I'm sorry.
Shame on who ever has misled you.

At the very least, start by separating the frogs from the anoles for now, until you can house them all separately.

You will have the advantage of getting advice from many very experienced members here on FF that have many, many different species of frogs.

Brace yourself for a barrage of responses regarding never mixing species.
Please use this ( your thread) to keep all of us posted moving forward.
We are here to help

If you do a simple" Frog Forum" search or google search on the topic of mixing species you will able to understand the reasons this is never a good idea. This topic has been discussed over and over for decades.

Best, Lynn
