Dude are you special or high? Everything you have given adivice on is wrong or in accurate.
Before you start talking smack and insulting ppl let me set you right. The flowerhorn unless its a zz will lack red in the chest and especially in the mid/end of the body. The "red that spreads out" is often only found in SRD which commonly have a flower marking ( i know u need help to understand what the flowerline actually is) most kamfas, faders/gb, golden monkey and texas reds will not have this marking.
The "flowerhorn" fish is a hybrid cichlid, i know
A
animal
guy cichlid is a big word let me explain. Cichlidae
Traits are as followed:
º a single nostril on each side of the head/forehead
º a spilt lateral line
º a specific structure of the. ear bone
º intestinal tract is also different
A flowerhorn is a hybrid consisting of many central America cichilds such as Amphilphus and Synspilum, first bred in the early to mid 90s in Malaysia. As a result the hybrid fish often has a nuchal hump (horn) and a flowerline wich are the black markings that run along the lateral line (more specifically the second lateral line) hints the name Flowerhorn.
Depending on which strian of fish you have will differentiate the traits it will have.
Kamfa; a larger bulky build, normally white or yellow eyes that are sunken in, a small mouth with even lips, a fan tail and sometimes have a flower marking on the head.
ZZ/ Red dragons: rounded tail, a round large mouth with a underbite, normally red eyes that protrude out, a nuchal hump and pearls.
Faders/GB; a goden based flowerhorn, will fade as juveniles, often vivid in color as a adult and commonly red or yellow in color.
In conclusion you now see why your it is difficult to properly identify and juvenile flowerhorn especially with comes down to what strain it is I hope this helps you better understand the flowerhorn as a fish.
