Lovely to see the gerbils and Draco and Teep
I used to have an aquariam with tropical fish, not bettas though. I used to find them very relaxing to watch. My favourite was our apistogramma cacatuoides called Fred
He was such a character and I was so upset when he passed. I used to love our plecs and catfish too
My pet peeves...I probably have a lot of them
Which is also probably my worst habit, getting annoyed by too many things
I'm going to take your pet peeve QOTD literally and my answer is, people who say it's only/just a hamster.
