From the sticky:
-it's been set up for a couple weeks.
-no live plants.
-the filter says "C(UL)US listed E228699 2UW6 Ac 115v 60hz 3.5w 0.074a." I have no idea what this means.
-I'm not using a CO2 unit.
-The tank is beside a window but it's covered all the time so it probably doesn't get any natural sunlight, should I change this?
-I changed the water yesterday, probably like 30%, when I was using the gravel siphon thing.
-I feed the fish "Nutrafin max" Goldfish
food once a day
-I think the light is fluorescent, I turn it off at night for 7-9 hours.
I don't know the temperature of the tank but it's probably not that hot. I'm going to bring a water sample to my pet store tomorrow to get the parameters tested, I'll get a thermometer too.
I won't be able to get a ten gallon tank. Do you think I should get a different kind of fish? If so, what am I supposed to do with this one? I don't want to just take it back to the store. What if they kill it or something, since it's sick.
This is my first fish, so I guess I don't know as much as I should. I thought you could put Goldfish
in bowls and stuff anyways.
