Okay, so I have baby danios in a twenty-gallon tank w/ a sponge filter. The problem is that I have been in self lockdown for six weeks and am unable to get to the tank to care for them; they are six weeks old. I removed the all fish before leaving to go into lockdown but the danios bred. It is unknown when I can get into the building to get them. I can get the janitors to feed them but is there anything else I can do.
