I might go a school. I'm just dreaming up a tank ATM tho. Walmart misled me into thinking my puffer fish would do great in a freshwater 2.5 gal. So I upgraded her to a 5 gal brackish after I joined a month ago. I know she needs a bigger tank, but I've got 5 shrimp, proper filtration and a jungle of fake plants for her to play in. It saddens me, but I have to keep her in those confined conditions. It's better than her grave at walmart.
