First time posting here. I've been looking around the site and haven't been convinced on the method to get rid of the rot and not effect the catfish.

I have a 5in silver aro in with a 8in ripsaw catfish and noticed some fin rot starting to grow on the edges of the aro. He's in a 100 gallon tank with 2 marine land 400 filters. I did a 50% water change 2 days ago and I'm wanting to add salt and don't know how much. I plan on doing about a 25% water change this evening. How much salt should I add and also I'm assuming I should add it after the water change. I'm trying to not use meds unless it's necessary. Any advice would be greatly appreciated. Cheers!!

Can u post your water parameters? Just to get an idea if it's a water quality issue as this is likely the cause.

Post some pics.

Can just dab the areas with hydrogen peroxide dipped with a qtip and return back to the aquarium. That way won't effect ur aquarium or salt sensitive fish and avoid salt and antibiotics.

Are you certain it's fin rot? The aro MAY BE rubbing on something in the tank and/or rumbling with the catfish causing it?

Possible, but I keep a close eye on him and there isn't really anything for him to rubbing on. On the edges of his fins there are dark spots and also starting to look a little tattered. That's why I believe it's fin rot

Small aros get spooked easy and go biserk sometimes, bashing of every thing in the aquarium. This my happen when your not there to see, that's one possible scenario for the tattered fins. The other more likely cause is that you have ammonia present. This will cause deteriorated fin edges. High nitrates can cause fin issues with aros also. Test your water before your next waterchange and post them. Forget about pH...not important. Silver aros do fine in high pH. A consistent pH is all that's important. Whatever your tap water pH is what you need to go with. Messing with your pH will cause way more problems. I hope you realize silver aros get huge. Mine hit 22 inches at the 1 year old mark. You'll need to upgrade to a very large aquarium soon. My aro makes my 96" × 40" aquarium seem small.
