Can I add a pair of diamond gobies and purple tang to my 120

[joegoersch]

I have a 120 gallon reef tank (2 ft x 4 ft) with lots of live rock and 40 gallon sump with lots of LR and chaeto. Current inhabitants:
Mandarin Goby, nice and plump,
Starry blenny,
royal gramma,
ocellarus clown,
pajama cardinal,
pair of zebr bar goby,
purple firefish,
one spot foxface

snails, cleaner shrimp, hawaiian feather duster, zoas,


I'd like to add a pair of diamond watchmen goby (Valencienna puellaris) to replace one that I had which passed on after more than a year (one day stopped eating, next dead, I never figured out why).

In addition I'd like to add EITHER a purple tang or a two male (different species of) flasher wrasse-maybe McCoskers and Carpenter's.

Thoughts on how the purple tang would fare in my tank. Would it share the broccoli I feed my foxface ?:spin1:

No problems with a pair of goby's provided you purchase them as a pair. Purple tangs need a larger 6' tank, but a small one would be alright. (he will have pecking issues with the foxface, but should be alright with just the two)

I keep a PBT and foxface in my setup.

No experience with the wrasses

Agreed with sgt York. Tangs required 6' of swimming area. They love to jet for long stretches
