I’m thinking of pivoting my stock list to the following:
already have:
Pink streak wrasse
Gladiator clownfish (just 1)
Neon goby
Yellow coris wrasse
Court jester goby
planning:
3-4 Dispar anthias
1 sunburst Anthias
One spot foxface
Tomni or white tail bristletooth tang
3-5 chromis (this one I keep going back and forth on… not fully convinced)
do we think this would be too many/much?
I think with the anthias you just need to try to make sure you don't get 2 males. Even with all females, the most dominant one will eventually turn male.
As far as the bristletooth or tomini tang goes - I love my tomini. He has a lot of personality. He can be territorial though (he chases my diamond goby sometimes) so make sure you have a lot of caves and hiding places. Looks like you do (the tang will definitely claim one of those caves). Also I've learned tangs poop A LOT, lol, so be prepared to keep a close eye on your water quality. I think the white tails are really gorgeous, and they're similar fish so I'd go with the one that you like the looks of the most.
As far as the Chromis go... I've considered them as well, for some active colorful schooling-type fish. But, basically everyone says they eventually pick eachother off and you end up with one. I believe they're less likely to murder eachother in much bigger tanks where you can keep a huge school of them. Then the aggression is more spread out. Also they are prone to uronema.
Now the foxface - I've actually literally been going back and forth about getting one myself recently, partially to round out my utilitarian fish crew, but also because I think they're really cool fish (and had one in my dad's tank when I was a kid). Problem is, they get big (even the one spot)... a small one would be ok for a year or two in a 75 gallon from what I've been told, but you'd have to plan to rehome it in the future as it reaches adult size. I don't like the idea of having to rehome a fish that I've had a long time, so I'm thinking I'll pass on this fish. (I already will probably need to rehome my baby yellow tang in a few years if I haven't upgraded by the time it gets big). I've noticed the "foxface police" are the new "tang police" as well... lol. (I say this in jest, as they really DO have a point that these fish are probably much better suited to a tank over 100 gallons minimum). There are people who keep them in 75 gallons though and they do ok. So it always comes down to a personal decision.
Last but not least, I don't think your list would be too many fish (though I would do the anthias OR the Chromis, not both).
I keep a bit of an overstocked tank though so, there are others who may tell you it's too many. I believe in overfiltering to handle the bioload of that many fish, paying very close attention to compatibility and how you introduce new fish, and introduce them slowly - one or two every few weeks. (Except for the anthias - I'd add those all together). That way you're not overloading your biological filtration. You also want to look for fish that inhabit different parts of the water column (your choices look pretty good as far as that goes).
Just for comparison, here is what I currently have in my tank (and the order in which I added them):
Bicolor blenny
Pair of Darwin clowns
Tomini tang
Melanurus wrasse
Diamond goby
Striped fang blenny
Flame hawkfish
Captive bred yellow tang (very tiny)
The last fish I plan to add are a Yellowtail tamarin wrasse (being quarantined right now), and a small group of anthias (either sunburst or Evansi, haven't decided). MAYBE a small foxface... but probably not. I will probably wait for that for if/when I have a larger tank someday.
Hope this helped?
