Channa gachua. Tropical or sub-tropical??

Did he have them when you got it?
Looks a little bit beaten up from that pic.

If he didn't have them, it'd be a bit more worrying unless he squeezes himself into some decor and scratched himself;

He hade some of them before but I "think" there have been some more since I got him. He does some digging in the sand and sometimes under the root so maybe thats why. Atleast he seems fine, he is active and eats allmost anything a give him

I have tried to get good pics of him but that didnt happen so here comes another bad one, but atleast his dorsal fin is up. Will continue and try to get a good pic, gonna borrow a friends camera and see if I will have better luck. Got the temperature down to around 22 C (71.6 F) and he still seems fine
