Sometime before the start of 2006 I will be coming into possesion of a 10 gallon tank, and I would like to keep a couple of red tailed sharks in it. I would like to do the research before I make the decision whether or whether not to get them. I need to know just about everything. What kind of food, are they good pets, how many, special tank requirements etc. etc. I have kept goldfish before, and my father has kept a salt water tank. I would greatly appreciate any help I could get.
