Several days ago I went to Petco, and made an impulse buy of a sick betta. Since this was an impulse buy after all, I also bought a 2.5 gallon tank kit, gravel, and decor. I am quarantining him in a 1 gallon tank to treat him for finrot; he won't be ready to move into his new tank until the middle of next week, but I decided to set it up anyway.
One of the plants I got is a sort of magenta color; I thought it looked very pretty. But after a few days I looked at the filter and saw that the sponge I use in the filter cartage had turned sort of pinkish.
I did buy this plant at Petco, so I would assume it's supposed to be fish safe. But should I use it if its color is leeching into the water?
