Alright, well I have a couple of questions.
First, I had a preggo "male" guppy that began to give birth about three weeks ago. She started to pop out one and 30 minutes later, it was still halfway in. We tried to pull it out a couple of times, but it was stuck pretty well. She never gave birth to that one or any of the other ones. She lived about a week after that and died with the baby still stuck. Have any of you ever had this happen before?
Secondly, I was stuck with one guppy, one neon tetra, and one bumble bee goby (it was doing fine in freshwater btw). So I went out and bought 2 more neons, 2 male guppies, and 1 female guppy 2 weeks ago. The neons were small in comparison to the one I had and the guppies looked a little weird, but otherwise everything was fine.
The next morning, one guppy was dead. It looked like it might possibly have ich, so I treated the tank and everything was fine. The next morning, one of the smaller tetras was dead. The day after that, another guppy died. Last week, I purchased 3 more gobies. A couple of days ago, 1 goby died. Yesterday, the last guppy I bought was dead. This morning the very last guppy died. I checked the water parameters on Saturday and there was no ammonia or nitrites and the nitrates were fine. I'm left with my original tetra and 3 bumble bee gobies... What do you think happened?
