Hi guys, ive currently got a 30 gallon community tank ive been keeping for almost a year. A friend of mine is selling some of his fish and selling me the tank their in once their gone, its 300 litres. I want to set this up and use it to start keeping flowerhorns in a few months time. But, ive heard from a few people that I cant keep them together. However, ive seen many youtube entrys of people keeping up to 6 adult flowerhorns together and others with 10's of young flowerhorns. I was hoping of getting a male and a female. Im looking for a good source of information on keeping that particular species. Any advice anyone can offer is fully appreciated!!
