Hi! so i bought a tiny 2 gallon tank at petco a year ago and all that i have in it is some plants... BTW, it does have a heater and filter! I want to start stocking it and i want to know what will fit. I know that it will be small for fish but i want to know what shrimp, snails or fish (besides bettas) that will fit. Thanks so much! I love shrimp espessially if they are colorful and snails that are unique looking!
