Who Gives A Fish Forums

I just did a 50% water change, scrubbed the sand and all the decorations in the tank, and cleaned everything else I could reach. Now one of my yellow labs is swimming around in the middle of the tank like normal, which is a big relief. I'm not sure about the other one, though - he's still sitting at ...

I'm starting to think those fish didn't just die off from a minor issue. Nitrites and ammonia, they don't just magically disappear within a few hours. It's likely they were suffering from ammonia poisoning, and that's what ultimately took them out.


I also read that mollies need hard water and ...

Sorry for the late reply. I've been meaning to call the city to get the parameters of the tap water, I'll do that and post the results. I managed to squeeze in a 35% water change and cleaned half of the gravel, but I was pressed for time. Today, I'll finish cleaning the other half of the gravel and ...

Update: I know it's been a while, but things have taken a turn for the worse. Those fish I mentioned earlier all died, and every other fish I've added to the tank has met the same fate. Right now, my parameters are looking okay, I guess.

Ammonia is at 0, Nitrite is 0, and Nitrate is 0. My pH is ...

No mollies with cichlids, they'll get killed when the cichlids mature. Temperature's fine at 78F, no need to raise it.

It's either water quality, soft water, or a disease that's causing the issue. Did you drain and refill the tank before adding new fish, and use a dechlorinator to remove chlorine ...

Update on my tank: it's been a while, and I've had zero luck - every fish I've put in has died, one by one. I've made some changes and my current parameters are:

Ammonia's at 0, Nitrite's at 0, Nitrate's at 0. My pH is still 7.8, but I did lower the temp to 78 degrees for a bit to reduce aggression ...

Hi All,

I've got a relatively new tank (about a month and a half old) and I've already lost three fish.

First, I had a yellow lab (about 1.5cm) with a patch on its stomach that never healed. It stopped eating, sat at the bottom, and was breathing hard. I figured it was an ulcer, so I separated it ...
