Long story short - My nearly empty 36 gallon ( has maybe 4 inches of water ) still has some zebra danio fry I am trying to catch. They have been in this tank unfiltered and unheated for 3 weeks now ( I moved all of the fish over to my new tank 3 weeks ago ) These were "surprise" and unexpected fry but I want to save as many as I can. I have been transferring them over to a cycled 5 gallon QT tank for over a week now. I think out of the 15 or so that I transferred over initially, 8 or so have so far survived. I still have maybe 10 + fry left in the tank I want to catch but these things are SO FAST and so tiny! I can see them when I am looking at the tank from the front but I can't see them as well when looking from the top. Ive been using a clear plastic cup to scoop them with ( I think a net would be worse ) I'm really dying to empty this tank soon . How do you catch these guys?????????
