Hello! Well, when I bought my fish, I got a 2.5 gallon tank. And I hated the fitler, so instead of putting a sponge in it, I just bought a bigger tank
Fishie's tank before:
I had to scoop him out and put him in a small container while I exchanged the current tank. He was so mad! haha
So then, I went to the pet store with my boyfriend and made him carry everything, and I got alot of new stuff for the fishie tank!
Fishie's Tank After:

I love this pic cause you can see his reflection in the glass :P
Look at his little black cave! (what he is swimming towards) I bought it for only ten bucks off a website. Its perfect and tiny for him, and ceramic.
Happy fishie!
Tell me what you guys think!
