Just bought a 30 gallon for my 3 goldfish yesterday, they are very happy in their new home. I did alot of changes, i bought 4 plants and put them in terra cotta planters in the back of tank. Had some big river rock and now added some smaller ones. The filter is great, it is a power filter that i got with the tank kit. I bought bubble wall, looks really cool. My otto, Mr. Clean loves to play in the bubbles alot,

. This is the best looking fish tank for my goldfish yet. I LOVE IT AND MY FISH LOVE IT TOO!!!
