I have a SRD, bout 4.5-5 inches. Had him about 5 weeks.

Tank parameters
Ph: 7.6
Am: 0
Nitrite: 0
Nitrate: 0
Temp Currently 82.7

55g tank (plan on going 125 when he gets bigger) Do 50% water changes twice a week. Bare bottom tank, only a terracotta pot, big sponge filter, 4 inch air stone, and heater in the tank.

The shop I got him from was feeding him big fella extreme. I already had grandsumo waiting for him. He ate that fine for about a week. After posting here prior other foods were suggested to optimize health. Purchased blood red parrot + by hikari, and new life spectrum ultra red. He loved the parrot food, wouldn't touch the ultra red. Ate well typically 4 pellets once at morning once at night. I would tend to give the sumo in mornings and parrot at night.

He eventually started not eating the sumo and only the parrot food. Then after about a week he wouldn't eat the parrot food either. Held off feeding for 3 days and tried again. Wouldn't eat sumo. He ate 2 pellets of parrot food only at night. Temp was 79 though all this. Then he stopped eating completely again. Increased temp to 82. No changes, went out yesterday and got hikari cichlid gold. Puts it in mouth and spits it out. Thought maybe it's too hard so I soaked 2 gold and 2 parrot pellets for about 15 min this morning. Wouldn't touch either.

I ordered Xtreme big fella, and Excalibur (original) online this morning. Be here in about a week. Xtreme cause that food has history with him so hoping it fixes the issue and I got Excalibur cause I've heard good things about it and figured it give it a shot since nothing seems to be working.

He's still very active. Sometimes he lets me pet him sometimes he goes crazy biting me, I have a ping-pong ball that I out in the tank and we boop it back and fourth to play. He constantly does backflips and likes to swim upside down in little bursts. Typically when he does eat the parrot food it's red/white string/red/with string. If he ate the sumo it was same but brown instead of red.

I've read online the white stringy could be sign of him shedding intestine lining due to digestive system being irritated.

I refuse to give him frozen or live food. High risk of parasites, and in my history with other fish once they have that stuff it's a pain to get em back to pellets so I won't even go down that road with this guy.

Anyone have any ideas of what else to try? Just starve him until new food arrives? He always seems to be searching the surface for food but won't eat anything I give him. Like I said he's still full of life but trying to be proactive before this turns into something more serious. Thanks for your time.

*Edit: forgot to add the primary filter is a fx4, the sponge is just supplemental filtration.*
 
I think you are looking at the issue wrong, it's not that your flowerhorn suddenly stopped liking any particular pellets.

I think it's intestinal issue.

Does he have white stringy poop?

I would start with adding some salt in tank, might need other medicines.
 
Not just white stringy.. when he does eat it's like a strand of poop that is 1/4 inch red, 1/4 inch white, 1/4 inch red, 1/4 white.

I was thinking possible hexamita but his color, activity level, etc is all great. He just isn't eating and when he does is like a pellet a day.

Up ur water changes. Tank not cycled yet. Keep adding beneficial bacteria. Try feeding some garlic mixed with the food. If ur able to get some hex shield then it’ll be better to feed for now till it eats better.

Everything these guys have said... also... stop trying to pet him... it may be fun and it's not something you CANT do once in a blue moon but it stresses them out.. they're biting you because he doesnt like it lol... I would also suggest not feeding at all right now until your sure the tank is cycled and his poop stop being stringy.. maybe try feeding him peas though they may help clean out his system

Just wondering how the OP made out with his Flowerhorn? My new Flowerhorn is acting similar to his, but I’ve only had mine for about a week.

Mine just does not seem to attack or want food like I’ve seen so many do in videos. He eats some but is very picky and will only eat one certain type of pellet. I have tried frozen krill, he will eat that but it seems like it takes him forever and mostly he just plays with it.
 
Ended up dosing him with general cure. He finally started eating again after 3 weeks. He only eats soft pellets so I used to soak em in bloodworm juice. Thinking that's what caused a lot of issues. Now I hatch brine shrimp, pour em in a small silicon ice cube tray and make my own brine shrimp cubes. Feed him 7-9 pellets once a day in the evening. Has been fine since. Got him a gf. Have my first batch of fry. About a month old. Shes due to lay again this weekend.
