fruit flies. the vampires hunt them, I've seen in videos.
So do they use the water much? in and out? all over? I'm trying to decide how much water to use in my next tank (which you saw) and have never seen video of them in the water...
Nice setup chris. I really like the whole vampire crap setup!
I have a viquarium and enjoy it very much. I have a FBT and 2 FBN. I havent had any problem with them co-habitating. In the water side i had a female betta that i had to put in there cuz she was very mean to my other fish and she did just fine. I also had ghost shrimp in there. Not sure where they went,(i think the newts at them). My tank size is a 29g so i have lots of room. Very heavely planted. Its like a jungle in there. lol They all love it tho. Good luck and post pics soon.
