I'd like them to get to the 3-4" mark quickly, I know it won't happen. I kinda bought them as a spree of the moment kinda thing. I was expecting the vender to bring some sumbu to go in that tank but brought only 1....but she brought alot of these. Ive not not wanted these lol. I have a 180 to set up for these but man they'd be lost in the 180, their lost in the 125.I'm actually looking forward to the slow growth. Less maintenance and food bill.
