It's ‘lesser killie’ fish, also called a Dwarf Livebearer...personally I find it interesting you would argue with me quite angrily about you keeping a puffer in a 2g in two separate threads and then jump in here to repeat the info I gave you...just interesting...fishcatch22 said:maybe get a betta, or an african dwarf frog, or maybe a pair of endlers or least killies, or cherry or ghost shrimp.
