Don't keep Flowerhorns in the same tank as a sting ray. I put a stingray in my 30 gallon and the flowerhorn was eying it but it did nothing. The next day the sting ray was torn up and eventually died later that day. 
Word of advice....

a 30 gal will hold 5-10 newborns for a few weeks if needed .. he didnt say anything about the size .. i assume that FH was not that big as well since it was in the 30 to start..azn_boy AKA fish freak;3411961; said:you put a sting ray and fh in a 30 gallon tank??
