Have a Nuvo 30L (36 x 13 x 13) 20 lbs LR and LS.
Tank is 4 months old. Presently have:
Pair Kaudern cardinals
Male Flasher type wrasse
They all hide in the rocks until feeding. Would like to get something in there I can actually see.
I had a horned blenny in another tank that was amusing to watch. However I don't think my tank had enough algae for it to eat and I lost him after 2 months.
Thanks.
A flasher wrasse needs a larger tank; cardinal fish don't do much.
