I had a neon tetra die should I replace him?
So I had a school of 6 and one passed. It was shortly after bringing him home so I’m not sure if he just didn’t survive the stress of the move? My tank is cycled and no ammonia spikes or nitrite spikes and the other 5 seem to be happy and healthy. Should I just keep my school at 5 or is it better to add 1 so they feel more comfortable with the bigger school?
