Killed My Guppies Somehow
I had six guppy fry and bought a new tank to move them to once the tank cycled. Well, the tank cycled. I added Fluval cycle and did the API Water Test Kit. Everything was good, so I thought. I took the fry about 3 weeks old by now and moved them to the new tank. Within about two hours they were dead. I don't know what I've done wrong. I'm so upset!
The readings were good. No ammonia, nitrite, PH about 7.4. The heater was working and about 77-ish.
What did I do wrong?
