Pajama Cardnal Fins Bitten or Something?

[wfo115]

Have had my tank for 5 months now, Tank mates have been the same for 3 months. Added two Pajama then two false clowns then two purple fire fish and one lawnmower blenny all over a 2 to 3 month period. All fish I have looked great and behaved perfectly. Today I came home from work and my smaller pajama's fins are torn or bitten or something any ideas. I do have two koralina power heads. Nobody seems to be harrasing him at all? Any Help would be great. I have included a picture of both pajamas 1st one is the small one with the problem, second one is the bigger one Thanks.

watch them, at night too turn off lights. I have one pajama cardnal. They do act like damsel when DARK. IF not being attacked, fin rott.

That definitely looks like aggression to me. Rot has a white haze and is often streaked with red. Those look like clean bites. Watch your fish carefully, but from a distance. They are likely not to bite if they know they are being watched.

Woke up this morning and pajama is alive but sucked up against the intake of the overflow just hanging there. What fish do you think would be the aggressor. The other pajama or the lmb,clown,purple, also I have a emrald,a cleaner shrimp and peppermint shrimp.

Yeah, and fin rot occurs over time, not overnight.
