Yeah, that is what I assumed. Thanks for confirming.Ugh, YES! I tested the ammonia when I got one of my female bettas. Between 2.5 and 3.0. I didn't know it was possible.....
That's about twice as tall and a little bit wider than the cups at my LFS.
My experience of UK stores have been filtered individual mini tanks. Or a betta (one per tank) with another species of fish, or in breeder traps. Have only seen pictures of bettas in cups and glad haven't seen that sort of thing here.. It is appauling..
