I used to have Cichlids in a 38 gallon tank that always looked empty until feeding time. I then had Parrot fish when they first came out as a new breed. Now I have a salt tank. Started with seahorses but the tank was too small... 20 gallon extra high with 10 gallon sump. So now I have a Clown Fish, Royal Gramma and Yellow Clown Goby.... had a Firefish but it jumped the tank

I also have two ponds... one is Koi with waterfalls 11x16, the other is small pond with fountain 3x4.
My house is for sale and don't really know if it brings the value up or not. We will see.
I remember when I worked in pet store, we would check person's tank real well before selling them discus. If I remember right, the water had to be real soft and ph high with no nitrates. They are beautiful but I like my salt and look forward to getting a bigger tank when we move so I can get seahorses again.
