My Zebra danio is laying on the bottom of the tank
I had just recently purchased a 30 gallon tank to have zebra danios.
Some history: I have already had fish before in my life. I built a type of current thing for my fish have a heater on 75 have pH, nitrite, nitrate, and ammonia hangers in my tank , two filters, and all the necessary conditioners for the fish.
The weird thing: I cycled my tank with four of these fish for a month and two weeks. The test hangers read perfect levels, so i went and bout four more, due to the size of my tank. I also acclimated them through drip for two hours. But when i added these new fish almost all of the fish started to sit at the bottom like they were schooling. They were not swimming around much after a day of being in the tank i checked the levels of everything and it all seemed to be fine.
Please help me figure out why they are sitting at the bottom of the tank?!? I thought at first they were sleeping but only one seems to do this regularly, and they all follow after. Maybe because they are a schooling fish?!? I have no idea? Any Ideas?
