You can also add aquarium salt to help..
A safe dosage amount is 1 tablespoon(15ml) per 10gallons..
It's not a big deal, don't worry too much; happy aroing.
I will try to set up a cam next time she eats nightcrawlers! She is very shy so she might just not do it in front of the cam! You just might she a big blur swoop by and snatch the nightcrawler! LOL
The tank has a hood but she hit it so hard it opened and stayed opened! I have cushioned the inside with bubble wrap to prevent further injuries! She usually doesn;t skim the surface much like most aros so the only time she ever tends to do acrobatic is feeding time!
