1. I have sand around 3-5mm mixed into my sandbed in my wrasse tank and they were all good with it.
Halichoeres species are the most robust but the other genera,
Pseudojuloides, Macropharyngodon and
Anampses, should also work with it. I’ve had
Cirrhilabrus,
Paracheilinus, and the above genera (plus some other sand sleepers like
Hologymnosus and
Xenojulis) and whilst I have about 3-4 different grain sizes mixed in, they weren’t affected by the 3-5mm.
2.
C. aurantidorsalis should be good, I’d add it later down the line just to make sure the other fairies/flashers have a chance to settle.
3. Whilst it hasn’t been an Eight Line, I’ve had both an
Attenuatus and
Hemitaeniatus (the closest relatives within the same complex) and whilst they could become more pushy, as long as new flashers/fairies were added in groups they weren’t a major issue. I have been looking at going for a couple of eight lines in my 5 foot 180G recently as I’ve been replanning the wrasses I go for and what I do. Below the answers to the above post is the way I’d do the wrasse groupings with these additional
Cirrhilabrus/Paracheilinus.
4. Exquisite Firefish would be a good choice if you wanted a pair of them, however if you wanted a group of Firefish the best species I find is the
Magnifica (Reds) to mix as a group as they are naturally communal whilst the other species in the genus prefer to be more solitary or paired.
5. Yep! If you went for a different species it could work, I’d personally go for the
Acanthurus and a
Zebrasoma, as opposed to a
Ctenochaetus as I have had them become unnecessarily aggressive towards wrasses. As for which Acanthurus to choose, I’d recommend a Gold Rim personally as they have a smaller maximum size overall and are the most peaceful out of the Powder Tangs (
A. nigricans, A. japonicus, A. leucosternon &
A. achilles).
6. Yes you could have another
Genicanthus, I’ve seen a few tanks where they have 3-5
Genicanthus together, both pairs and singles. If it was me personally, I’d go for a Bellus and Watanabei or a pair of Watanabeis. I find nothing can beat the colours of a good male Watanabei.
7. Other fish I’d look at are mainly small species like certain Cardinals of the
Ostorhinchus genus, but also the
Prognathodes butterflies. They’re smaller so don’t often target large snails, crabs or shrimp. I’ve had the Marcellae before in a display tank, but I personally love
P.
Aculeatus (Caribbean Long Nose).
8. How I’d add the new/potential ones I’ve recommended;
Group 1
- 8 lyretail anthias
- tesselated blenny
- orange spotted blenny
- Exquisite or Red Firefish
Group 2
- bell's flasher wrasse
- red tail flasher wrasse (Paracheilinus rubricaudalis)
- Cirrhilabrus Bathyphylus/Nahackyi
Group 3
- lineatus fairy wrasse
- girdled fairy wrasse (Cirrhilabrus balteatus)
- Cirrhilabrus laboutei
- Paracheilinus octotaenia
Group 4
- watanabei angelfish (female)
- achilles tang or gold rim tang
- purple tang
Or
- Watanabei Angel
- Other Genicanthus species
- Acanthurus or Zebrasoma tang
