Where to start? Well 3 yrs ago I went to walmart and bought 3 fancy goldfish and 1 small random goldfish (I think it was just a feeder) and stuck them all in one of those little corner 1 gallon tanks. I didn't even buy the right water treatment (bought clear water instead of start right or w/e) and they all ended up dead in 20 minutes. Then I got a betta (2nd betta, first one died in less than a week from infection) and he lasted for 3 yrs. He lived in the little 1 gallon most of the time. I rarely did water changes (maybe once a week at best) and when I did, I did 100%. I was even using dish soap for a while. -_-
I knew he needed more room, just didn't have the cash to buy a bigger set up. But later I did end up getting a 10 gallon for my birthday. I ended up plopping my betta & an apple snail in there. I didn't cycle it, never EVER did water changes (only top offs). The apple snail died 2 months later. At first I thought the betta tormented it to death....he did eat its eye thread thingys. Anyway, now I'm pretty sure it's because my nitrogen cycle was all crazy.
And now my latest error? Well this week I bought an automatic feeder for my fish (going on Christmas holiday soon). Problem is the feeder is bulky & requires me to leave my hood partially open. This is problematic because I have a psychotic cat. I don't know why I thought it would be okay. Anyway, tonight I noticed that one of my little rasbora has a piece of glitter stuck in its gill. This is likely from the glitter on my tree skirt which my cat likes to play with. My guess is he was sticking his paws in the tank. So anyway, guess what I decide to do? I decide to try and extract the little piece of glitter with a thimble. Um. Yeah, it didn't work out. It looks like I may have harmed the little fish more. There's redness and URG. I don't know what I was thinking.
