The blue sided fairy wrasse we had was about 4" and in a 120g. After observing this fish for many months, before its unfortunate tank disaster demise, I believe this fish deserved the space afforded in a 120g. Its swimming habits and natural curiousity definitely makes this fish a large tank specimen, ime.

Oh I agree, I thought I was already hinting at that a 20g was not a good long term home, but if that was not clear then I apologize. However mine are juveniles, and are OK for now. They are growing fast, however, and they will not be in the 20g for much longer.

BTW I see I made a mistake, I said they max out at 4", in fact it is 5" (according to some sources).

(My pair's next home will be >10 times larger than their current home. :razz: Hmmmm, approximately 14 times in fact!!)
