Curious why you hate your L200 I love mine.Ooohh puffer would be cool the tank is pretty much maxed out with two little bichirs (grow out) and a raph call and L200 (hate this thing)
Its my sons tank so as long as hes ok with rehoming some fish i'll let him choose between the puffer or loaches.
How would a pea puffer do with the polys ?
I agree with the loach idea also. I always had clowns before but I am thinking of getting to yoyo loaches.
