Man you guys have some great tanks. I used to have two I had a 90 gal set up for fresh water and had a 120 for salt water, had a puffer, a lion fish,and an eel and damsels, but the lion fish ate them. I could hand feed the lion and puffer,s , lost bot during the big ice storm in 94?. The salt water tanks can be the easisest to take care of after it sets up , not as much cleaning and water changing, but I used a big bio filter set up. I lost close to 1,000 dollars worth of fish and live coral. had an arawana in the 90 fresh, they are my favorite fish he could be hand fed also. I wish I had the room to have my dream tank, I want at least a 500 gal built in. A friend of mine in BG had one and it was awsome it was salt water. After the bio system gets kicked in salt require less maintance than a fresh but the fish are costly.
