Quick Update - He has buried the past few nights and is coming out a few minutes after lights on in the morning. He's definitely less skittish, eating like a champ, and has a ton of personality. The goby has also found the sand and they seem to switch off - at night the wrasse gets the sandbed and during the day, the DWG gets it.
So I'm considering ordering two more of the Blue Star Females and perhaps 1 other wrasse (leaning towards the Exquisite Fairy Wrasse) but a few questions:
- Any concerns with the Exquisite Fairy and the Blue Stars in terms of compatibility?
- LA doesn't list any of the Exquisite Fairy as male, so I'm assuming they haven't transitioned. Is it normal for them to transition if there is another male in the tank even if it's a different variety?
- A sub-question of this, in general, can you keep more than one male wrasse in a tank or it should be 1 male to many females?
- Assuming I purchased the Exquisite Fairy, would all of this be ok in a 20 QT? To recap, the stock list would be 3 Blue Stars - 1 male, 2 female - , 1 Exquisite Fairy, and 1 Diamond Watchman Goby. In case it matters, the filter is rated for 50 gallons, so I'm not overly concerned about the bio-load but don't want to spike ammonia (especially if I end up treating with Copper after everyone's doing well).
