Hello,
I've been treating my tank for an outbreak of fin rot and have lost 2 fish, 1 guppy and 1 panda corydoras. When removing the fish I've noticed that they both developed a red spot. This red spot only seems to appear when the fish have died. I just wanted to check that this isn't something pointing to another illness which I've misidentified as fin rot. If anyone has any ideas on this please let me know, I'm very concerned for my other fish.

How much of the water do you change? 20%
What do you use to treat your water? Prime and API Stresscoat alternating
Do you vacuum the substrate or just the water? vacuum the gravel
*Parameters - Very Important
Did you cycle your tank before adding fish? yes
What do you use to test the water? API Master Test Kit
What are your parameters? We need to know the exact numbers, not just “fine” or “safe”.
Ammonia: 0
Nitrite: 0.25 (we had a nitrite spike and I have been doing daily water changes to get this under control)
Nitrate: 30
pH: 8.0

What brand of food do you feed your fish? Hikari Frozen Brine Shrimp, Tetra Betta Plus floating mini pellets, Omega One Freshwater Flakes, Api Bottom Feeder pellet with shrimp
Do you feed frozen or freeze-dried foods? Frozen food once a week
Illness & Symptoms
How long have you had this fish? Guppys and Corydoras 6 weeks, Betta 2 weeks (my guppies and corydoras are from my larger tank, they are only in this tank temporarily)
How long ago did you first notice these symptoms? 4 days
In a few words, can you explain the symptoms? Ragged fins with white edges or blotches
Have you started any treatment for the illness? Yes, I've been using API Melafix for 4 days
Was your fish physically ill or injured upon purchase? No
How has its behavior and appearance changed, if at all? No, they are all still eating and still have the colouration they had before, they're all moving and see fine. So far in this tank I have 2 Guppies and 1 Albino Cory who show signs of fin rot the others aren't displaying any symptoms whatso ever.
Explain your emergency situation in detail. (Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
4 days ago I noticed one of my guppies had ragged fins, at first I thought this was physical damage because I didn't see any whiteness on his fin. I kept an eye on the tank that day and noticed an albino corydoras had bits of his fin missing but also saw some whiteness there. I immediately started treatment for fin rot. Since starting treatment I've lost 1 Guppy who didn't show signs of fin rot and 1 Panda Corydoras who did show signs of fine rot. Both of these fish developed a red patch under their skin in the same place but on different sides. I didn't notice this red spot before they passed so I think it's postmortem but am also concerned that there might be something wrong with my fish which isn't finrot. I would be grateful for any help or suggestions anyone has. Thank you.
