not only did i learn some about my fish i also learned some philosophy!!!!!!! i bought a 75 gallon and made a species tank for my dragons got some nice black sand and am now in the slow process of turning the water brackish for them. i have noticed an immediate change in their behavior....they dont hide as much any more and swim around alot more i guess they are happier without all of the other fish and with the growing salinity. all the other fish are in my 29 gallon and doing well. thanx for all the replies and help.
