Urgent Care :: Bump on both my RES's claws now?

[xDiiaZz]

Hello, I have two red eared sliders, one is 1.875 inches and the other is 1.5 inches. I noticed the bigger one has a bump or something on his left front claw, then the next day after I left them in the sink to feed them, I noticed he just obtained another bump on his right front claw. Therefore, he got the second bump when I left him and my other RES in the sink; I think his first bump was also from when I was feeding them. I have attached a photo of his first bump, does anyone know what it is and what might have caused it and how to cure it?

it seems be a wound. possibly from biting bet the 2 hatchlings... i got this a few years back when my turtles were still hatchlings.. observe them awhile to see whethether it occurs again. in the meantime.. ensure that the water is clean to prevent any infections.
my turtle cured it on its own the moment i seperate them during feedings..

It looks like an infection to me, though it could be an injury like swiltz mentioned. It's hard to get an idea of it's severity from the picture, so I would recommend having a vet check it out since the nail bed can be infected.
