I also owe a lot of "thank you"s and apologies to the people on this forum.
Thank you for saving my fish from living in a small aquarium and from dying.
Thank you for the advice and answers to all my questions.
Thank you for giving me the courage to make a change and confront my mother about getting a bigger tank.
I am sorry that I had to be the newb that didn't research stuff before getting the fish (well, the only fish I got by myself were the swordtails, on which I did a bit of research but not enough)
I am sorry for making these newbie threads/posts constantly about minor stuff (sorry to Tizer mostly on this one).
I am sorry for being slow in acquiring the things I need, but I am getting them, and as soon as my card is released (they said 5 working days), I will get the nitrite kit, then when I get the rest of the money I'll get more stuff.
And most of all, sorry for being stubborn but it's hard to change and give up on a hobby I've been carrying on for many years even though back then I knew next to nothing about fish keeping.
