My flowerhorn is acting weird

[Flowerhorn gang]

I have just moved him to a bigger tank around 2 weeks ago. He was doing fine until yesterday after I changed his water and put some algae solution, he has been acting weird since. Could the chemicals cause him to react this way, because in the past when i use the algae solution, he was not affected by it. Should i try a salt bath? I will be monitoring him to see if it is a parasite infection. Anything i should be doing now? Thanks in advance

Just wait and watch, doesn't look serious right now.

Ok, but he does not show interest in eating at all. Dropped a pellet in and he ignored it??

Check ur water quality first. Could be from the meds as some algaecides are irritants to fish. What does the poop look like?
