First Betta.
We had neon tetra in a 34l tank (I know, but we were very novice)
Lost the last tetra about a month ago, so rescaped the tank (adding driftwood and more new plants, and getting rid of the previous tacky ornaments)
Got this boy today. Said I wasn't going to get a red crown tail but ended up going for personality - this guy was super chill in the store, but he's actually perked up a lot since joining us.
