How many mated pairs of fish do u have

[Delphinus]

Oh I forgot about my failed attempt at pairing up golden dwarf eels. That was a mistake. Lesson learned - some fish you can make a pair of - but some fish you have to buy as a pair.

I want to one day get a male crosshatch for my female - but I'm afraid to do so. Have heard of cases where it's gone well, but also heard of cases where it's gone poorly.

The biggest eye opener for me are butterflies. Everyone thinks they're so docile (well maybe not everyone but it's something I do hear time and again). Truth is they can be downright nasty to each other if they so choose.
