what Tang ?

I like to get a Tang for my 75g but not sure what one to get. I had a yellow one (stupid powerhead) killed him. Most poeple tell me tankgs need +100g size tanks to be happy. Is this true? are there smaller ones that will fit in a 75g and be happy? What do you guys and gals think?

75 is kinda small, the bristletooth tangs would be best suited for that tank, koles, flametips, striated, etc. They tend not to be as "flashy" as other genus of tangs though so if you plan to upgrade eventually than I would just wait and add a tang you really like. Don't want to get stuck with a fish that you "settled" for and then can't get rid of. And buying a little one until an upgrade doesn't really work because a healthy tang grows fast and they are heavy on the bioload.

I had a Kole tang in my 72 bow front, and it was fine. I didn't have it for much more than 8 months though. I noticed that it became more active after adding some Chromis to my system.

looks like i need to find a mine tang

you can get a regal tang, (dora) they do just fine in a 75 i had mine in a 75 for 10 yrs before i upgraded to my 125 and he did just fine.
