Help! what is this in my tank
 

Hello,
I have a roughly 5 year old diamondback terrapin and a painted turtle. I noticed a fleshy/stringy material near the Diamondbacks vent today, but I did not see an injury site nor did it look like worms. I am calling the vet tomorrow, but wondered if anyone had any insight. I noticed the tank was slightly pinkish tinged today and was alarmed when I saw this unknown item at the bottom of the tank. They both are acting normal. Alert, eyes are clear, and a healthy appetite. Please help with any information on what could be a possible explanation. Attachment 822244Attachment 822244

Here is the other side of it. It is about the size of a pen cap.

I could be incorrect because of the state of the tissue, but it appears that one of your animals is a male and the penis has died and detached.

I will move this to the veterinary section for you.

That would be extremely helpful. Thank you so much for your input, it is really appreciated.

It is most likely that the DBT everted his penis and the painted turtle bit the flesh. The result is what you see. Not much the vet needs to do. Possibly prophylactic antibiotics, but the blood vessels should have sealed by now and the amputated area should heal (but not regenerate) without intervention of any kind by yourself or the veterinarian. You will want to monitor things, of course. If behavior gets iffy, if the animal stops feeding for long, or if the swimming becomes impaired, I would say a rushed visit would then be wise.

Poor little guy cant imagine what he went thru.
