One of the first times I spawned Blue Dempseys... I removed the brood from the parents very very carefully by siphoning them into a 1 gal pitcher... very very carefully removed the excess water... very very carefully carried them across the room over to the fry tank that was very very carefully set up for them...
... Then my girl let the dog in the fishroom which attacked the front glass of a fishtank right beneath me (he and that Oscar had a long lasting battle), I stepped on the dog's tail or leg (not really sure), it yelped, I jumped Blue Dempseys went into the air... Most of the water & fry landed on the dog...
I saved a few but not very many...
We all make mistakes... just do your best to pull a lesson out of it... I ended up moving my fry tanks away from the tank the dog liked to attack the most...
