I am setting up a brand new 3.5 gallon planted tank for a Betta. I started cycling the tank last Tuesday and purchased three plants from the pet store (Hornwart, Amazon Sword, and Water Sprite.) On Sunday, I spotted a tiny fry swimming towards the top of the tank, and I have found a total of 6 since then. I hadn’t put any fish in the tank at this point, so I am assuming they hitched a ride on one of the plants. I think they hatched from eggs based on the fact that I didn’t notice any until Sunday. Since then I bought some First Bites for them to eat, and I have been doing daily water changes while the tank cycles.
Does anyone know what kind of fish these could be? They’re extremely tiny now and difficult to get a clear photo of. I am attaching a photo of one, as well as photos of the 3 tanks that my plants came out of at the store to help narrow down what kind of fish they could be.
