mystery fish

[CHEEZY]

So I have a ten Gallon tank that I haven't had any fish in for like three Weeks now it don't have filter or heater just a tank sitting with gravel and water now all of a sudden there is baby fish swimming around in it zebra Danios I think there is eight of them what should I do?

Get the heater and filter back in there, they won't survive otherwise, bring them up and also do you have another tank or something if so get a breeder box and pit them in that in a running tank
