yea..i must agree with u. i have read from the books too that they could be kept in a colony...but no such luck for me. they kept going for each other s throat, and that happen after 3 years of living together.(i have 7).the winner kept watch in the tank while the losers all 6 of them stayed at the corner and refused to stray far unless food is offered. thats the reason why i stopped keeping them a few years back. ah, kigoma cost about 5000baht(rm500) for a 4 inch fish while burundi cost about 800baht(rm80) for a 5inch one.this is thailand. i sure cant afford a rm500 fish my friend. so how much does a kigoma cost in K.umpur?
