Aggressive Tank Size

[timia]

First of all, I'm new and this is my first post!
A couple of questions for you Aggressive experts out there.
I'm planning a new tank - aggressive fowlr and want to get your opinion on my stock list and a tank size to keep at least most of these fish. I'm looking in the 240 - 300 range....hopefully more towards the 240 end but that is why I am asking.
I'll start by saying I like triggers! Secondly, I chose the following fish based on them being maybe slightly less aggressive than other choices and also maybe a little smaller when it comes to their adult sizes.
Picasso
niger
pink tail
yellow tang
powder blue tang
kole tang
Emporer Angel
Lunare Wrasse
Bird Wrasse
Snowflake eel.
Also, in your aggressive tanks, are any of you using crushed coral or does everyone use sand now? If you use sand, is it on the bigger size (grain size)? Seems to me that if you use the powder fine sand, every time a big fish swoops by it would get all stirred up? Maybe not. Also, what is the going recomendation for depth of substrate?
Thanks for your help everyone!!

I use argonite, Go with a 300 the bigger the better with agressive fish.

welcome to the board, bigger is better, it will give you more options. When doing multiple triggers be careful of aggression, and stick with least aggressive, I would drop the picasso for a blue jaw, crosshatch, or hawian black.
Good luck!

Good fish choices, IMO, just don't go too fast; regardless of tank size. I personally think a 240 will accommodate most of these fish. Triggers have have individual personalities; but with a lot of room, I think your 3 choices will be fine. If you get a nasty one, trade it for another.IMO; crushed coral is one of the worst choices for substrate. Its structure traps a lot of crud and that results in nitrate production. Please search this site; you'll get plenty of opinions and more reasons to avoid it. Keep us posted.

I also would advise against using crushed coral for the previously mentioned reasons, also it can be too sharp for sensitive skinned fish and eels

Ialso agree with the Crushed Coral statement. Not only for those reasons, but the sand just looks better in my opinion. It makes the tank look more realistic (and clean if you ask me).

Do you have to vacuum the sand at all then or is it best just left alone?

I should probably also ask this question. When I'm looking at the various sands out there, many of them give the average grain size like somewhere between .5 and 4mm. What size sand are people suggesting these days? And at what depth? Guess this would go along with my prior post of "Do people still vacuum the sand or what that just CC?" Seems to me if you had the sugar fine sand, if you tried to vacuum that, it would all just get sucked up??? What brands are you guys using?
