Is it safe to keep different species of Fairy Wrasses in the same tank,ie a Scotts, Lineatus and a Pink Margin?
If you read the whole thread you can see that people like Bronco have many different fairy species in one tank.
The key seems to be avoiding having species that look similar that are also the same size, especially if they're added at about the same time.
I have a large supermale Pink Margin, no other fairies yet (I do have a Candy or Twin-Spot Hog, closest thing to another fairy - no fighting observed, but the Candy Hog is a lot smaller.)
However, they do look a quite a bit like Lineatus fairies and they're closely related varieties. I'd say that a Lineatus and a Pink margin might fight if they were similar sizes and added together. Cook's don't look anything like either of them though and I guess they shouldn't fight.
I think there's some speculation that Pink-Margins and Lineatus fairies may not even be sepearate species, isn't there? Much is unclear about species relationships in fairy wrasses because DNA testing hasn't been done; some variants of species may be different species alltogether, and some different species may just be color variants of one species.
Anyway, once I got my Pink-Margin I took Lineatus off my wish list; something like a Laboutei that doesn't look like either a Pink-Margin or a Cook's may be better for you.
