i have no self control and i bought another boy today. it was love at first sight. and of course i got all the stuff for him. he’s very afraid of my phone so i cant really get a good picture but he’s a very beautiful pink/purple/red. his tank just looks so plain, i would like to put another fish in with him but i doubt i can. i know i could add a snail or some shrimp but i would love another small fish. any species that can go in a 5.5 gallon?
