hmm. It does look like an ulcer. Thank you for posting the article. I was also reading up on some of the things

mentioned about ulcers as well. This is a new possibility!
Whichever course of treatment is chosen, the aim should be for the problem to be resolved in two or three weeks. If the problems persist then a different treatment plan should be considered and an investigation into the cause of the infection should be carried out again. Dirty pond or tank water can certainly cause bacterial infections, particularly if one or more fish have existing injuries. Attention should be paid to water quality and the filtration system to ensure this is working efficiently. Overcrowding can also contribute to disease as it can stress the animals and may even cause fights, and regular maintenance of the tank should also be thorough. Cases of ulceration should be addressed in a systematic way as they can persist if treatment is not exhaustive. Trying different treatments in succession is unlikely to be effective and may even make the problem worse.
Overcrowding:
I don't think overcrowding wasn't an issue cause just had the 3 fish in the 55g tank. All were 5 inches or less. Then the ornate was in the tank for about a month by himself. Convict cichlid died (was super bloated and or/ maybe super fat from months of my dad overfeeding) and I rehomed the pike. Immediately after cichlid died, dosed with prazipro.
Water Quality and maintenance:
I did change the maintenance routine. From my dad occasionally cleaning the tank(maybe 1x a month.....the water typically smelled for some reason)...to me changing it every other week. Then I got my bichir. He was in the tank for two months without any problems, doing every other week WC of 25-30%. Then eventually went to every week cause the tank smelled sometimes. Then the scratches showed up in December. Then the wound on his back. Could have been from abrasions, burns, or punctures, no idea. WC went from every week 25%, then to 50%.
Would a maintenance change like this cause the ulcers? Seemed like they did get worse. Every time I when I got the water tested(maybe 2x a month at first), water parameters were considered "normal." 0,0,0-2for Ammonia, Nitrite, and Nitrate. Phosphate was always dark navy(through the roof) and pH was 7.6....I did use neutral regulator for a time to get the pH down to 7.3. However, made phosphates worse, so I stopped. Fish store said they were "normal" parameters were normal, except for my high pH. Could high phosphate or high pH be the culprit?
How do I know if the water is dirty, if parameters are "normal?" Seems clean, to me, but the tank is always tinted a greenish color, which makes me a little uneasy. The water itself is clear. Also the fact that the water could "smell" slightly foul, is peculiar to me as well. I've never had water smell before....especially since I'm good about doing water changes. Don't know if it is from the driftwood or the glass, tank, or maybe just the water itself? Also i know that there appears to be green algae growing in the silicone seals of the tank. There also was red circular algae in the tank and brown algae on the walls.
Could there be bacteria in the brace of the tank at the top? I know it was leaking at one point and I never sealed it? That's my guess. Cause the smell is located all around the border of the tank. Kinda smells like mold....maybe this is getting into the water? Again this is all speculation.
That's literally everything I can think of. lol. It's a lot I know. This has been a mystery.

How do I test the water to see what bacteria/parasite is present? Could it be that the city water/ hose water supply line to my house is of poor quality? Could it be there is a bacteria culture growing somewhere in the tank or filter?
how do I see if the filter is working effectively? It's a penguin 350 HOB, been replacing cartridges every month, and putting in poly-fil. The grates are not in there anymore, but the biowheels are still present.
How do I treat the tank and clean everything in it? Should I bleach everything and start over?
THANK YOU EVERYONE FOR YOUR ENDLESS PATIENCE, ADVICE, AND SUPPORT FOR ALL OF MY QUESTIONS. I've never had problems EVEN CLOSE TO THIS with a tank before, so I really appreciate the troubleshooting and advice.
