This is the current condition of my flowerhorn pet. My flowerhorn has not eaten a single thing in 10 days apart from that if you carefully observe it you will see that my flowerhorn is getting hiccups (or something like that). For medicine, someone has suggested us to keep water temperature exactly at 28 degree Centigrade and suggested us two medicines bactinol and paracidol. We have been doing 40% water change daily and have been giving him medicines. Can someone please help me with this. I am really worried for my fish. (Apart from that he had skin peeling issue from which he has recovered now this had happened a week ago)
 
Unfortunately, when a Cichlid goes on an extended hunger strike there are really only three possibilities, none of which are good.

Intestinal parasites, bacterial infection or Bloat, which eventually leads to an intestinal bacterial infection.

You might try to entice the FH to eat live foods. Then feed food laced with antibiotics.

Medications dosed into the water column don't usually cure gut infections. Medicated foods are the best option if the affected fish continues to eat.

Thank you so much for replying. Could you please suggest me some live food that I can feed my flowerhorn. (Also, recently I got some dried shrimps for my flowerhorn, is the bacterial information because of that?). Can you also suggest some more cures for it please?

Sir Can you please suggest me some small live fishes which my flowerhorn can eat?
 
Are you seeing any white fecal casings, often stringy or mucus-like, can mean stress, diet issues, or a healthy mucus lining, but when accompanied by symptoms like bloating, not eating, or wasting, they often signal internal parasites (like Hexamita/Spironucleus). There are different ways to treat. In general ingesting the medication is by far the most effective.
#1 You could try something like bloodworms coated with Seachem Focus and metronidazole just to see if the fish will eat fed daily for 7-10 days.
#2 If it still refuses food then you could try treating the entire water column, start with one gram of metronidazole per 20g daily for 10 straight days(100g would be 5 grams). I do daily water changes prior to dosing as metro doesn’t have a long shelf life dissolved in water.
#3 I have also had great success injecting 12mg metronidazole with a little water to squirt directly into the gut with a plastic pipette doing this daily for 7 days for 7-10 days. Take the fish out and place on a damp towel and slowly insert the pipette into their stomach(this is more stressful for the fish and yourself).
#4 I have no personal experience but RD has this as a sticky in the health forum. https://www.monsterfishkeepers.com/forums/threads/treating-hexamita-aka-spironucleus.523470/

These are the pipettes I use.

I get metro in bulk from Jack Wattley discus.

Once finished ultimately you’ll need to address the cause to prevent future occurrences.
