Almost all my angel fish have their dorsal fin clamped, non of the other fins are clamped at all. The water parameters are ph: 6.5 nh3-nh4:0ppm. They are all still eating, no lesions or injuries. No pop-eye or bloat, no swimming funny, no fin or tail rot, no ich or velvet, no apparent fungus, no cloudy eyes, no fighting (other then the little one that fights with his reflection in the mirror), total of 6 angels and 5 of them are clamped. Someone please help!

Any major chances in the tank in the passed few days (big water chance or temperature chance) things like that?

nope Im going to do my water changes today, havent added any fish or chemicals and I have a thermostat heater so it should keep it at a constant temp, every time I look at the thermometer its been the same temp.

I would go get a 10g tank and QT those fish unless you have a tank already for QT. Without any other real signs it is hard to tell.
