My husband had an aquarium over 25 years ago but I was never involved. This is totally new and foreign to me so I want to make sure I do the best I can. Right now we are just starting to cycle our 84 gallon tank with 5 zebra danios. I know it will take a long time, but we are in no rush and just enjoying watching the danios dart around. We eventually plan on getting 3 pitcus catfish, probably 5 tiger barbs, a keyhole chiclid and a red tailed shark. Looking forward to reading all the information on the forum and learning a lot.
