Hi guys, planning on purchasing a rack system.i plan on buying 3 females and 2 males i have done some research but i have only bred redtails in the past so sizes were much larger i use to use boaphile racks (jeff roone) what size do you guys recommend if i get his rack or is there a better bang for your buck else where...also i would rather buy a rack that i can change tub size depending on age/// or buy one thats gonna last rest of there life and i can always seperate space so not overwhelmed
