I have a pregnant neon tetra. I have no idea what should i do? can someone give me advice?
Happy to hear that! Your fish will be OK. Just give them enough food and prepare them for breeding with things like maintaining water quality and controlling the temperature. You can also add catappa leaves to make it feel more comfortable to breed.
In addition to preparing the tank to the correct temperature, you should move the broodstock to another tank to prevent the eggs from being eaten.
