what type of tank mate is suitable for a flowerhorn thats at about 8 inchs in a 90 gallon tank the the flower horn gets really stupid iv noticed with other fish in the tank so im lookn for a tough fish
yep 90g just isn't big enough. unless you had a pair. if you like the orange of a red devil. then get your self a parrot and put it in there with the fh. that's about the best you can do with that size of tank.
