Angelfish and electric blue acara fin rot?

HI everyone, for some weeks I've seen my babies angelfish and Electric blue Acara flashing on the sand and rocks and vibrating the body and fins, sporadically, so for lacking of other signs I kept observing.

I noticed some angels with ripped dorsal fins, and lacking one of the filaments of the ventral fin, and today my EBA with his dorsal fin ripped, and one of the juvenile angels with stringy white poop.

All the fish still eating like crazy, no spots, no hiding or slow moving but I notice the male EBA a little touchy, he snapped one of the angels really violently when she got too close, which he never did to any other fish, even when breeding.

So here is the video and photos for analyzes, I put a mirror that I use with him for photos, so you guys can see better.

Thanks in advance for anyone who can help!

 

Sounds like they are shaking off parasites that are irritating them, also causing aggression because of their discomfort, and both of those issues causing damage to fins... check your parameters first, in case that is the cause of the irritation, if parameters are fine I would do a water change then treat for parasites. (Water change first because most treatments need you not to change water again until treatment is complete).

They look fine to me. I see no fin rot and only some minor tears. Aren't they a little crowded in that tank? The EBA may be a little agitated because of that and the "snapping" at the angelfish may be because he is feeling stressed.

Is a 47 us gallon 180 litres, with 9 juvenile angels and the adult EBA, do you think is overcrowded? I might try to sell some of the bigger ones...
Look at the video, they are loosing tissue in the upper fin and shaking a little bit like something is bothering they never did that.

Do you think a treatment with sea salt would help the fish deal with the parasites? Sea salt is easier to get for me than the parasite medicine, also I don't know for sure which one to use...

Yes it can be used effectively, though I have always been afraid to use salt, myself. If you follow the directions very carefully, though, using it should be absolutely fine. I would have said it was flukes except for the stringy poop, which suggests worms, but either way I have read that salt can be an effective treatment.

Hoping someone who's used it personally will jump in for more specific advice.

Hello R...

If the tank was mine, I'd start removing and replacing more tank water. Work up to the point you change half every week. Add a bit of standard aquarium salt to the new, treated tap water. A rounded teaspoon for every five gallons. Do this from now on to improve the fishes' immune system and to discourage the growth of a potential virus or parasite. This should restore your fishes' general health.
