As i was looking into my Biube last night i spotted some very small fry amongst the media.I assume these are danio fry as i have three zebra danios in my tank along with some guppies and 5 other tetras. The thing is i have had these fish for over three years and have never noticed any fry before, do they have to be a certain age in which to breed they had been chasing each other for the last week or so so i assume that was what they were doing. The fry were all over the tank glass this morning now they have gone into the gravel i spotted one on a plant leaf a minute ago. Will any of the fry survive there is a lot of plants around the bottom of the tank crpts,anubais and java fern.What about feeding them will they pick things of the media and plants.Any other info would be grateful. Thanks
