The thing about raising FlowerHorn is that you could start off with just one 10 gallon tank and the next thing you know is that you are and will be surrounded by tanks just like if you were at the aquarium. This is the same outcome that happened to all FlowerHorn Enthusiasts, Hobbyists and Breeders that I know. But having a fish tank filled with water doesn't mean it will be capable to keep a FlowerHorn well and alive... These are the best water condition for your FH.
PH is 6.0 to 7.6
Temp. 82 to 86
and they are also at best potential with clean water.. meaning it is best to do a 10 - 25% water change every 2 weeks interval and also it is beneficial for your fish health to add conditioners and aquarium salt for stress coats.
