no visable signs of whats knocking off my fish

  • We are currently upgrading MFK. thanks! -neo
I just got over something that sounds the same. One tank (after a friend brought me 10 albino aneus) got fin rot and ich in a bad way. I treated with salt and increased temp (85F). Boosted the aeration to compensate for the increased temp. I treated the fungal problem with malachite green. The fungal infections cleared up but, I was still losing fish. I snipped some gill tissue from the latest floater and found alot of bacteria in the tissue. This didn't concern me too much since the gill from a necropsy. However, I also noted areas of necrosis and atrophy of the edges of what should have been viable tissue. I don't have a means to culture out a sample so, I have no way of proving whether the bacteria are gram-neg or gram-pos. So, I began a 10 day treatment regimen with tetracycline (for both gram-neg and gram-pos) for a bacterial infection secondary to the fungal infestation and the fish cleared up and perked up and the tank stopped suffering losses.
 
my tank is bare bottom, ill start my salt again. there are no visible signs of ick on any of the fish though. they all act perfectly normal, nothing unusual. Now that i increased my filtration rate by atleast 5time i hoping that will have some effect along with adding the salt back
 
How many days did you continue treatment right after ich seem to have disappeared? Usually, you need to continue 6-10 days of ich treatment after the last spot disappears so you can take advantage of destroying the invisible trophonts.
 
I worked at a petshop and I remember trying to add salt to certain fish tanks. It seems tiger barbs, neon tetras, and cardinal tetras are sensitive to salt. Not sure if things have changed with salt since then. I also remember getting shipments of clown loaches and they got ich about a few days later. So I tried using that ich medicine made for loaches and catfish, and it never seemed to work, so I used the full str ich medicine but only used half the dosage and the clown loaches wouldn't get ich. Hmmm, this was probably pointless to say.
