for our 6 year anniversary, my gf wanted a tank for her little fish, see all my other tanks are big fish or well not little enough to fit in there mouths. I got a 150 XH with stand for cheap. This tank will be tetras, guppies, and swordtails. first question; how do you manage a tank that size, lol didn't realize till I set it up; I am 6'2 and can hardly get my hand half way. beside peaceful cichlid what is a large fish I can get as a "centerpiece"... my stock so far will be 10x Buenos Aires, 10X bleeding hearts, 10x red eye tetra, 10 guppies, 2x BN pleco and a few swordtails. any suggestions on another school, barbs maybe?? idk. This is mainly my gfs tank, so that's why a few smaller schools than a big one.
