So what your saying is Velcro the bottom...Eheim Feed-Air. Hands down best one Ive ever used (of about 7 or 8 different ones) Just be careful if you have them over open water, they are kinda poorly balanced and even a slight bump will send them plummeting to a watery grave.
I tried that as well, works a little better, but still a good bump will pop it right off the velcro. They are good feeders, just use caution around them if you dont want them to sit in bags of rice to dry out.So what your saying is Velcro the bottom...
