I bought a 2.5 gallon tank and put a fish in it. He died. I didn't add enough conditioner to dechlorinate the tank is my best guess.
Cleaned the tank thoroughly, conditioned the water as read on instructions and the tank sat overnight. Next day, I went shopping and purchased Picasso. He was placed in the tank after doing the chemistry mix and temp acclimation by floating. He loved it. For a couple of days. Then, he just floated around at the top and became disinterested in food. Wednesday night, I took him out and put him in another smaller tank and today, he is doing a lot more swimming around. He's eating a little, but not much.
Also on Wednesday night, I cleaned the tank (and all the stuff inside), conditioned the water, blah, blah, blah, and added Redmond - my most "fiesty" one. Now HE'S not moving around much and not eating much...
The only logical solution I can come up with is that the water (which is treated separately from my other water as I fill the tank directly from the faucet) is not getting as well treated as the other water I'm using which goes into 1 gallon jugs, treated with Prime and Stresscoat (both) and I have to be honest, I add more than the directions call for. 2 teaspoons per gallon of each. I do that because I think we have hard water (calcuim deposits on faucets and showerhead that require a vinegar soak every so often). In the 2.5 tank, I follow the directions on the bottle, hence, less conditioner.
I'm thinking I need to do at least a 50% water change and use the water from the jug to refill the tank. Is this logical or not?
I just don't know what else it could be. The filter is off and the heater is keeping the water at 78. Which is slightly warmer than the other water he was in, which was 74. Hmmm...
I don't know. Any ideas?
