I am going in for livebearers and catfish. The common guppies, and platies, less common porthole livebearers, and some rare phallichthys tico coming on Tuesday. ALso planning to order some heterandria. Would like to go on getting more into the rare livebearers. I like the way they interact with each other- they are quite sociable.
For catfish, I have a pair of bristlenoses (perhaps my favourite fish) and a group of corys. Hoping to get some rarer loricariids or some whiptails one day. Corys are great fun to watch, not least when they're spawning. And the bristlies are just lovely fish, fun to watch, fun to see them interact, interesting spawning behaviour.
