Does anyone know why my flowerhorn has stripes all of a sudden?

When my kamfas were younger they used to stripe up when they slept. Once they woke up and ate theyd color up again.

well it can be stress but when mating that is not stress and they stay that way,put a mirror against the tank and you see a change of color this not because he is stressed out from poor condition or health problems he is pissed . bars does not alway mean he stressed he can be it great health good water conditions not breeding just pissed

Exactly, my fish are in very great condition, eating well, and swim actively and occasionally get the stripes when they start getting all nuts and aggressive. I guess aggravation is a type of stress on the body though =P

If you've made all the proper accommodations for your fish, proper ph range, temp, etc, then this isn't uncommon with my experience in FHs.

doctor horn,
Yes, the fish eats well.

Thank you guys! The fish seems to be well. eats well. I do see it being aggressive toward other fish. This is my first FH. If I got another FH in the same tank would they fight?

signs of stress maybe

2 flowerhorns in 1 tank will fight. Unless you have 180+ gallon tank and its heavily stocked I would not try it without a divider.

 

[doctor horn]

if you have a male get a female

Like Camph said, wouldn't recommend housing 2 in a small tank. The dominant one will continue to grow and the other will be stunted. Not to mention, the dominant one will beat the hell out of it. Even with male/female breeding pair, often times you will see people use a divider with a pot plate on the bottom of each side.
