damn.. he was really a great animal lover. even if other people thinks he's stupid or silly he's still 1 of a kind. there are only a few people who could do what he does. he would definitely be remembered.
RIP mate!
its better to keep your flowerhorns alone in a single tank. flowerhorns are very aggressive fish and are very very territorial. all in all i have 7 flowerhorns and 5 of them are all in a single tank.
they dont need any tankmates though. and if u put them in a single tank they will show more...
