At the risk of being totally and completely flamed by the "80 gallons per goldfish" crowd, yes. That's close to 15 gallons per fancy, or 20 for the first and very close to the recommended 10 for each subsequent. Moors can get pretty large when they are taken care of the right way. I love to see a couple of really beautiful fish in a well scaped larger tank. If you can go larger, that's great, but the 29 would suffice for a while.
:iagree: While 29 gallons might be a little tight, as long as you have plenty of filtration (more than 10x gph) and keep up on your water changes, I would say that it is enough for 2 black moors. I would also recommend going with a bare bottom tank as it will be easier to clean and since goldfish are very messy, it will make maintenance of the tank a lot easier. I will also guarantee you that you will not regret keeping the goldfish 1 bit! If you would like more info on goldfish, check out the forum on kokosgoldfish.com or pick up "Fancy Goldfish" by Erik L. Johnson. Here's a link to the book:
