I need a subject matter expert to pitch in on the best way to raise fry. I’m trying to raise about 10 from a late season spawn, so I brought them in and put them in my plant aquarium. They are just a mix of comet and maybe common, just as a test to see how they turn out. At about half an inche or so long each, I’ve got them in 5ish inches of water, with the dirt and plant matter in there. I’m doing frequent partial water changes to try and keep the good going, and remove any excess gunk. The only filter I have is for a bigger aquarium, so too strong for them. They are doing good, I just want to know what to watch out for for quality of life defects that might cause them problems later in life. The survivors will go back to the pond next spring, and yes, I’ve got a larger aquarium for once they are bigger. How fast do these little things grow anyway?
