thank you for all the nice comments.I have 6 tanks just for polys,two of them are big.The biggest one i have is a 21 inch endli and the smallest is an albino senegal about 2 inches.I still have a bunch of room in my tanks.One of my tanks looks empty until feeding and there are 35 in the tank.There are many kinds i still need and will get as well as i will not get any more sens,endlis,dels,laps,or ornates.
