Nice fish - ZZmalau and it's a male.
Potential troll? Seriously? I don't know if your advice is just taken as truth 100% of the time because of your post count, but:
"I bought a FH last week from petsmart."
1. Yeah right. Don't even TRY convincing someone you know what this is, let alone that it's anything besides a crappy red dragon. (Sorry, truth.)
2. Male? This fish is what, 2-3" long, you have no idea what it is. Seriously.
Maybe you're just trying to make it so this dude doesn't flush it if someone tells him it's a mediocre, unidentifiable fish, but stop.
And yeah, anything bought at Petsmart/co is just that, unidentifiable. Even if you grow it out, it doesn't matter what it LOOKS like, it was born in and grew up in a gigantic farm tank with hundreds to thousands of other "flowerhorns". This kind of thread and these types of comments are poisonous to the hobby (specifically, the keeping of flowerhorns) for those of us who take the time to research what needs to be researched, and buy fish from reputable, knowledgeable breeders, typically outside of the country.
