I recently came back from a long vacation of a month and a half. I immediately did a 90% water change on my planted 20 long. There are 2 Colombian tetras, 1 panda Cory (other 5 died while I was away, I’m assuming nitrate poisoning due to lack of water changes), and 3 nerite snails in the tank. I’m bummed about losing the cories. Anyway, as I was doing pruning and maintenance to the plants, I spotted a couple Colombian tetra fry. I have no idea how to take care of fry and need advice/tips. I have a spare 1 gallon which is cycled but has nothing in it that I am going to use to house them. So far I have caught one and moved it over. They are about 3 mm long and I think there’s only a handful left. Any feedback would be greatly appreciated!
