The past two nights I have been having my tiger shrimp die. It's been one each night and I'm not sure why. My levels haven't changed or anything. We got them about a month ago, we were thinking maybe they were sick? But would it really take this long for them to start dying?

What temp do keep them at? Tigers are quite prone to bacterial infections especially at warmer temps. Also, if they are only dying at night is it possible that O2 levels are dropping? If the tank is planted, at night plants use O2 and release CO2. Do you run an air stone or have good rippling at the surface? Just my initial thoughts. If it were me I would probably do a good sized water change and increase aeration. If they were still dying then I would medicate for bacterial infection.

I keep them around 75-77. My boyfriend just told me that the temp did some how rise about 5-6 degrees the other day. We actually just purchased and air stone last night to hook up and put in the tank today. If it is a bacterial infection what would you suggest buying to cure it?

Now that I'm really thinking about it, the first one did die shortly after the temp rose.

We also noticed that lately they have been swimming higher in the tank than normal. I'm not sure if that has to do with anything (i.e. low O2) or not.

I know folks who have used maracyn2 and/or melafix for bacterial infections. However, I think you already found your problem. 80+ for tigers is bad, even 77 is pushing it. Even worse if there isn't alot of surface movement since water carries less O2 the higher it gets. I would try to keep the temp around 70 with an airstone personally.

We turned the heater off, but the house is pretty warm now because the air broke, so we are keeping a fan on it to try and keep it as cool as possible till it gets fixed. But we haven't had any shrimp die since we turned the heater off and got the temperature down a bit.

The fish are LOVING the air stone. My panda corys like to ride the bubbles up. It so fun to watch.

Good to hear. What is the temp in the tank down to now?

Its at 72 right now, but the house is at 64(it was fairly cold out last night). We cant figure out what is keeping it warm. Especially overnight. I'm afraid when it warms back up again and the temp is going to rise back to around 74-76. We keep the house around 70-72 in the summer.
