Tape should not make them go bad.
My last batch on Otohime for the first time use (from beginning day 6) is at day 11, most have headbands, and I have never had such an active, good looking bunch. I fed NHBS exactly 3 times.
Other things I did differently with this batch: twice daily siphoning and replacement with fresh saltwater on drip, one more airstone, bringing it to 3 seperate air sources.
It's my personal best, and there are at least 100 larvae/juveniles in there! Let's hope I don't blow it!
