I think I have Betta-specific MTS.
I can't stop myself from buying anything which I think is a good price, that I could fit a betta into. I don't see why I feel the need to do this
Gah, know the feeling. Whenever I go out, I can't help thinking 'ooh, I bet this holds over 1.5g, that would make a good experimental betta home!'... Note, this is for items such as mixing bowls, measuring jugs, bins, and anything else made out of plastic. I have to almost physically make myself walk away from the big plasic brewing tubs....
