okay, I just read the post about the amonia… but here is the thing, I don’t know anything about fish tanks and fishes. I bought my goldfishes last week, and my husband was going to be caring for them… he is out of town, and I need to save them… or I will loose them all. My fish tank is small, with a filter systam and light. From what I understood, I only needed to change the water once a month. Now I am supposed to change the water??? How do I do that? Can I use a cup and get some of the water out and just pour some more water in… I am so dumb. I really know nothing about fish… and the worst is that I bought the fish for my 4 year-old girl, and I already had to lie yesterday to her when I found one of the fish dead. I told her that I took it to the vet and that in couple of days her fish would be back… now I have a fish that cannot swing properly and is curved, bent from the suckin filter he got stuck… I feel hopeless… I don’t know what to do… I am panicking here!
