Hello. I have two RES turtles, when i found them they were both the same size, now the once smaller one has had a growth spurt and doubled in size very quickly.
My concern is that there is a red tint of residue at the bottom of the tank, and it just started showing up. I am concerned that it may be blood? But then again it is a lot. And the turtles don't seem to be hurt. It smells terrible though. Does anyone have this problem? I am just hoping its not some sort of bacteria growing.
Thanks for everyones help!
