Do tangs really produce that much waste??

Not all angels nip, I've had quite a few that were model citizens, lemonpeel, singapore, white tail, emperor, regal. It seems that as long as you keep your fish well fed with a variety of foods they don't seem to stray.

Kole tangs still get too big. While they do clean glass and rocks quite well, they aren't small tank fish.

When you balance out what they do for the system, vs. what they take from it, its unequal. Tangs eat a lot, but they produce a huge amount of waste. Most of the food they eat needs to be added to the tank, vs. a fish like a sixline wrasse, who will eat pods, something the tank naturally produces.

Well i gusse i cant keep a tang at all then so im just gona get a lemon pell angle or somthing of that sort.:cry: :cry: :cry:

interestin' pic lol

Ok do you think this would be a sutible fish in my tank. My tank agine is 46 g and thos fish is rated uptp 50 g thats only 4 gallons to small) and the fish ihad in mind was a Mertensii Butterflyfish
My tank will mostly have about 50%sps.

Quote form Pet Solutions.com "Mertensii Butterflyfish, Chaetodon mertensii, is often found living on or around the reefs of the Pacific Ocean. Members of the genus Chaetodon make gorgeous inhabitants of fish only aquariums. Soft Corals and most Invertebrates should do fine with the Butterflyfish, but it may likely decimate Stony Corals, as they are a part of its natural diet."

This Butterfly feeds almost exclusivly on SPS.

Were are you getting your fish list from? you seem to be picking fish you can't possibly have success with

http://www.amonline.net.au/fishes/fi...h/cmertens.htm This is the fish you mean? I've never had one, and wow is it beautiful.
There is a butterfly called a Yellowtail (Chaetodon xanthurus), that looks almost identical except it requires at least 55g.

I know you have some SPS, and LPS in your tank alread. Do you plan to fill it with SPS, and LPS later?

Yes those sps and Lps and a bit of softies.

Is ther any tang sutible for my tank that I can keep in ther.
