hippo tang

[naesco]

What you need to know is that both the naso and the regal (hippo) tangs require tanks that are a minimum six (6) feet long which is 135 gallons.
This is the minimum requirements as per Scott Michael who is the guru or fish and their requirements.

The reason for the large tanks is that tangs, in addition to growing large, require the swimming room that longer tanks provide.

You already have one tang in a 90.
Please do not add another.
Thank you
