Raised 4 afrowana (african aro ) a little bigger than that. Yes good price, but very sensitive and mortality rate is high too. Bloodworms, flakes, and spongefilters, water changes a must..... or its bye bye afro.
HOB works too, but the strong flow might be too much stress for them. I took mine out and used sponge filters. Plus, it provides aeration and the africans eat off the sponge build up. So, it's beneficial IMO.
