Can you tell me who made the tank and filter and where you got them ?
it doesnt say, im guessing petso made the tank & the filter says "hawkeye 201"
Does it have a heater ?
Nope.
A light ?
yes, but i dont plug it in.

Do you do water changes ?
well, my fish only survived for about 2 weeks, and since the tank is empty, i dont think a water change is necessary.

Do you use a water conditioner ?
no. i let the tap water sit out a few days.......... prob not a good idea, huh.

Ok Sandra. You lost a couple of fish. We all have. Now you have learned a little something. How about this. You get a couple of Ghost Shrimp ( 8 for 1 dollar in my area) and you start over. You read up on fish keeping and save your pennies and if you like it someday you buy a bigger tank. Maybe a used one from some one in your town.
