Instead of just jumping in (no pun intended) to frontosa why not find out as much information as you can.
the 6 bands as you call them are known as Burundi.. Cyphotilapia sp. "North" (Burundi)
run a search on them and see if thisis REALLY what you want to get into, their a long term fish. They grow slow, they sometimes have special dietary needs, they can go belly up with out notice, known as "Front Float" in some circles.
when and IF they spawn it isnt so easy getting a female to hold to term much less getting the eggs from her in time to incubate them properly.
btw. 18.99 is WAY over priced. I've seen them go for 7-10 dollars. on the whole, burundi are considered the middle to lower class of the frontosa group. dont mean much to me though, I love them all the same.
