I've had dozens and dozens over the years of all kinds, here's some notes on different species:
- Lyretails have that brilliant orange that is just gorgeous and hard to compete with. I've never had an issue with getting lyretails to eat and they've not been skittish or shy at all. Lyretails have a tendency to be some of the most aggressive anthias species. Had everything from singles to groups of 3, 5, & 9. If kept in singles the male will dull out to a brown orange color.. my current one is still barely colored up after six months with some females.
- Bartlett's are a nice elongated type anthias that have a nice contrast in body color. Like the lyretails, I've not had issues with them eating at all AND they can be at the higher end of the aggressive spectrum. That said its seems like the aggression with bartlett's is generally limited to similar body style anthias (Carberryi, dispar, evansi, sunset). Had trios for years without issue.
- Carberryi are hands down my favorite in personality. I had a trio about three years ago, and had one die shortly after getting them. I still have the original pair and they are super mellow and rather than the aggressive nature of some species they just swim with one another and hang out in the current. Highly recommend - the color contrast isn't as great as a resplendent or an evansi, but still a beautiful fish.
- Dispar and Ignitus I have a hard time telling apart when I had them together. They ate ok but seemed prone to bacterial infections - at least moreso than the others I've had.
- Resplendents and evansi that I've had have always been on the shy side. I've had trouble getting them through QT and eating anything but live foods as well. The colors are ridiculous though. If you can get your hands on a good specimen, run with them.
- Purple Queens are divas and really hard to keep, so Id stay away from them. Never had much long term success with them.
Similar species can be mixed together without issue, so you can have two groups of three without much issue. I have a trio of lyretails, a pair of carberryi and single bartlett currently with little issue. They eat frozen, pellet and live once a day and have no issues at all. If it was my call, I'd go a trio of carberryi and a trio of bartletts. :)
