The ideal tank size for a single flowerhorn is about 75 gallons minimum. For most fish, the tank size depends on the size of the fish but not for this one. Irrespective of whether it has a short body, a round body, or is regular-sized, a minimum tank size of 75 gallons is ideal. Now, let’s go into a bit of detail about this. 

One or more of the original parent species was Amphilophus trimaculatus, and that’s the species that they most closely resemble, and behave like. They are tropical freshwater fish that originated in fish farms in South East Asia, and its in Asia that they are most popular.

They are so-called because of the “flower” marking and “horn” or hump on the head, though not all carry the markings anymore. There are lots of varieties including Super Red Dragon, Kamfa, King Kamfa, Thai Silk, Golden Monkey, Fader and others, and lots of different grades, body shapes and qualities. The fish with the best patterns and markings, and biggest head humps are highly prized and sell for large sums.
