Cagetheraven Posted September 8, 2022 Share Posted September 8, 2022 (edited) I purchased the med trio recommended on the website for treating new fish and plan on using it asap, but it has been misdirected to another town by the post office. As a temporary emergency solution I am using Tetra Lifeguard but I've lost at least two Corydora to whatever the issue with my tank is. Until this outbreak my parameters were looking good, but as of this morning they sit at Tank is a 36 gallon bowfront Temp: 78 degrees PH 7.4 Ammonia .25 Nitrite 0 Nitrate 20 (I'm new to trying to read these last two tests so I think it was) KH 100-200 (took 7 drops to change color) GH 50-100 (4 drops for color change) I changed out 5 gallons this morning before running out for emergency meds. I had a cory that was also not doing well but I think he has died just since I got back with the meds. Stocked with 7 rasbora, ~10 albino cory (the count is unclear, they don't wanna stay still for me to count heads) and 8 blue wag platy.

anitstuk Posted September 8, 2022 Share Posted September 8, 2022 I had this on ONE of my Harlequin Rasboras but it cleared up within a few days. How long have they had these white spots? 1 Link to comment Share on other sites More sharing options...
Cagetheraven Posted September 8, 2022 Author Share Posted September 8, 2022 I just noticed it earlier today and also found a second one with a smaller amount of it after posting this, they are swimming slower but aren't seeming hurt. I did see one flashing against a plant as well. Link to comment Share on other sites More sharing options...
anitstuk Posted September 8, 2022 Share Posted September 8, 2022 Are they swimming erratically or not eating properly? In my case, they seemed MORE active than usual and started chasing the others. Link to comment Share on other sites More sharing options...
Cagetheraven Posted September 8, 2022 Author Share Posted September 8, 2022 I hadn't noticed a change in their aggression but they are still eating, I will have to watch and see if they seem to go after anyone, though. 1 Link to comment Share on other sites More sharing options...
Colu Posted September 8, 2022 Share Posted September 8, 2022 White patches of there fins isn't ich what I would do is test daily and do daily water changes and add a double dose of prime till your ammonia constantly stays at zero and do a course of maracyn in food as the problems your having could be due to ammonia you could have had a spike and you missed it and now your seeing the after effects even ammonia at 0.25 can be harmful to sensitive fish 2 Link to comment Share on other sites More sharing options...
FishPlanet Posted September 9, 2022 Share Posted September 9, 2022 It looks almost like some type of fungus. Link to comment Share on other sites More sharing options...

That was my initial thought, because I think I've been seeing fungus on some of the dead/dying fish, but this looks a little different than what I had been seeing. Unfortunately I have no LFS nearby, and have to drive an hour to get to anywhere that has fish meds. Link to comment Share on other sites More sharing options...
quikv6 Posted September 9, 2022 Share Posted September 9, 2022 The ammonia may be the issue here. You tested at .25, but that doesn't mean it wasn't higher at some point. Small water changes with a dechlorinator that also temporarily binds ammonia such as Prime, would be a good path forward. Some salt could help as well.

Cagetheraven Posted September 9, 2022 Author Share Posted September 9, 2022 I thought salt would hurt the corydora? I have some, and have done another partial water change and checked the ammonia again but it hasn't gone down so it may be due to new fish added, I threw a bit of "Safe Start" in to hopefully boost the bacteria as well...

quikv6 Posted September 9, 2022 Share Posted September 9, 2022 Salt, in small doses, should be helpful. You can start at 1 teaspoon per 5 gallons. Link to comment Share on other sites More sharing options...
FishPlanet Posted September 9, 2022 Share Posted September 9, 2022 My betta had fin rot and I had a corydora in the same tank. I just used a smaller dose and it never hurt him. Link to comment Share on other sites More sharing options...
