I would keep doing daily water changes.... probably going to help the most, start small 20% at first maybe 20 % 2x a day, then move up to 50% a day if he makes it another week or so......this will probably be your BEST BET. you can medicate all day long, but if you dont fix the problem it will happen again and again.
With out knowing KH, GH and nitrate levels.... this is probably too fast.
For the sake of argument lets presume them to be sky high. Daily 10% changes for a week will reduce them to about half of what they are right now. If they are low, a 50% reduction wouldn't be a problem, but if they were high, a 50% reduction is a MASSIVE change. Going from nitrates of 10 to 5 is great, going from nitrates of 200 down to 100 is going to put a fish into osmotic shock and cause it to have the same symptoms this flower horn is experiencing. Its not actually the nitrates that cause the problems is the GH and the DOC's. (DOC's can't be easily tested for though, so use the nitrates as a gauge of where they're at.)
If the KH is low and you drop the GH, the pH will crash. That will kill the fish. If the KH is high and you drop the GH, the pH should remain reasonably stable.
A large fish in a small tank that is not getting weekly water changes is going to have sky high nitrates (which shut down immune systems), DOC's (which causes a list of maladies too long to print) and GH. Sky high nitrates and GH can be adapted to over time, but it renders the fish unstable and any major shift in them causes swim bladder mal function, kidney shut down, neurological problems etc... the entire ionic, and osmoregulatory capacity of the fish is thrown out the window.
Once the numbers are known, larger water changes can be suggested, but with out the numbers, the only safe bet is lots of small changes. If we knew the nitrates were only at 70 or 80ppm, a daily 20% change for a week followed by 50% changes for a few days would be great. But if the nitrates are at 200+, that would kill the fish.
AQUATiC213ZOMBiE you can hate me if you like and you can continue to insult me. I am trying to help you to help your fish. I have not said anything insulting to you. No one that can't afford to spend $7 on a test kit should be keeping live fish. If the $7 test kit is too expensive, then you have other priorities that need to be met before investing in fish like flower horns. If you can afford the test kit, but are simply not testing your waters, then perhaps some coaching to help you to understand what your pets need is most appropriate. However, you said you couldn't afford to test the water. I am not speaking poorly of you, I am not insulting you. Please don't insult or threaten me. I am trying to help you, perhaps insulting me isn't the best method to get my help.
