Hi, I've had a small tank (25L) for almost a year. I have 4 neon tetras, an otocinclus and a couple of guppies. I've had bad luck with the guppies, one has lasted the whole time, others die, I replace them, then the new ones die after a few months. I can't work out what i'm doing wrong, i've tested everything, levels are all normal, can't see any problems. So I want to give up on the guppies, any ideas for a hardy fish or two to join my tank?
Regards,
Chris.
