Hi everyone, I'm the latest new member joining you from frigid Manitoba,Canada.
In the few minutes I've been looking around, it looks like this is going to be quite the interesting site to be part of.
Unfortunately, I have a bit of an "emergency" question that I am looking for help with ASAP. I'll start out with this warning though. I know NOTHING about fish. Ask me anything about horses, and I'll tell ya, but fish are not my forte! (yet)
Quick background - we have a 70 Gal tank that normally holds 4-5 fancy goldfish year round, and several pond fish throughout the winter that come in due to our very cold temps outside. This year though, our fish decided to get "intimate" and our tank #s increased from 9 to about 125. I managed to find homes for most of the offspring, but still had about 40 little guys, plus our regular fish. The local supply store told me that my filter would keep the water clean enough, as long as it was cleaned regularily - however, that was very wrong. One of my fish began having severe buoyancy issues quite quickly, which tipped me off that something was not right. Last night I cleaned the tank thoroughly, but only removed about 1/3 of the water (as was instructed by the aquarium store). This morning I awoke to no fish swimming up-side-down, but several floating in that direction. More than 1/2 of my little guys were dead, and the rest are all gathered at the top of the tank "gasping" for air.
Can someone please help me!! Is there anything that I can do here? Why are they doing that? I am still losing 1-2 babies per hour, and I want to stop the carnage. Could I have added too much aquarium salt? Did I not use enough? If they haven't been near death by now (24 hours later), will they recover? Should I take out more water and add fresh stuff, or is it the change in the tank that's causing this?
Your assistance would be fantastic!!
