Am I maxed out on my 90g tank?

[stevedola]

In my 90g with 18g sump I have the following fish:
1 christmas wrasse
1 blue chromis
1 blue gudgen (like a jawfish size)
1 saddle back clown
1 flame angel
1 Cardinal fish
5 Lyre tail anthias

I have prolly 75 lbs LR and a Tunze Doc 9010 skimmer. I wanted to maybe add a sailfin tang or chevron. Possibly another wrasse like a Scotts.

What do you all think? I just dont want to over do it and run into issues.

I don't think you are over stocked, but no way would I add a sailfin, way too big.
Not sure if I would add the chevron in that size, a kole or tominni/bristletooth would be a better choice if looking for a tang.

 

[stevedola]

I was thinking that I was at max. Ill keep my eye out for a fish thats better for a 90...a nice fairy wrasse could work. What about another dwarf angel? Any suggestions? I just dont want to add something that fades into the back ground.

i'd go with the chevron personally

You've got 11 fish in a 90g tank with less than one pound live rock per gallon. I would say you are maxed out. I would not add any other fish, especially large ones like tangs.

 

[stevedola]

it was 75 lbs of dry rock...not sure if that matters to you but theres PLENTY of LR in the tank for biofiltration. Regardless, Im leaning towards not making an addition to the community.

wrasse wrasse wrasse!!

i'd go with the chevron personally

Chevron
tangs need 180 gallon tanks.

If we are talking about a 90g tank (rather than the 60g in your signature), 75lb rock is not "plenty" for biofiltration. If it was dry rock to begin with, that would mean even less initial filtration capacity (fewer bacteria than live rock). However, if the rock has been in the tank more than a couple of months, it is basically live now, and no different in filtration capacity than any other live rock.

Anyway, back on topic, you don't have plenty of biofiltration capacity in the tank with that number of fish and that amount of live rock. I think it would be wise not to add more unless something else goes.

Chevrons unlike most other bristletooths get big, way too big for a 90, the yellow eye kole would be a better choice if you are dead set on a tang. I'm not sure how the christmas wrasse will get along with another wrasse.

That sounds like a awesome tank. I think the question you should be asking is "should I add another fish". Of course you "could" but more fish especially larger fish like tangs means more waste and that means more difficulty in keeping your tank clean.

 

[davocean]

I personally do prefer at least a pound per gallon to aid in natural filtration, so I would lean towards adding more rock myself.
When I think of a stock list I always like to have one fish that mows on greens to help keep algae issues at bay.
In a small tank a lawnmower blenny may do that, in a medium size tank like yours a smaller tang may be ok.
I still think you have room for a small tang, and it's grazing could actually help in keeping tank clean despite your bioload, but I'd add a touch more rock, maintain aggressive skimming and stay on top of WC's.

If you want a tang, I would consider only the smallest species, like kole tang or Spotted Bristletooth Tang. The latest is a real beauty IMO http://www.liveaquaria.com/product/prod_display.cfm?c=15+43+2994&pcatid=2994

While I do agree that you are closed to being maxed out, I think you have plenty of live rock. Live rock weighs less than dry rock so 75 lbs of dry rock will be more rock than 75 lbs of live rock. Yes once the rock has been in the tank awhile it will become live but if you take it out and weigh it, it will be more than 75 lbs.

So how did Danskim do it? Granted he had a 300g, but a lot less rock/gallon ratio than you do I'm sure. I counted about 30 fish in that tank, not what I can't see.

I say a wrasse too, there are a lot of other factors other than live rock that aid in filtration. As long as there are no aggression issues, why not? It's your tank. Good luck.

Here is a link to his pic, too bad it is a for sale thread for that tank.

@Jeremy K- The rock has been in the tank for well over 4 years. It was marco rock and added a few small peices of established liverock to seed. What is not covered in coral is covered in coraline. We dont want a tank of just rock and I think youre missunderstanding the type of porous rock that was used. Ill try and grab a pic of the tank but there is by no means a shortage of liverock in the tank.

Also, the tank in my signature is my personal tank. The tank I am refering to is the 90 g tank I created for my father. I just assumed refer to it as my own than to get into explaining everything when I only wanted pick some other reefers brains to a question that my pops asked me. I set him up with his own tank and tell him how to maintain it. Hes a fan of reef keeping but not as experienced as someone thats been doing this for 10 years. He really wanted a tang but I shut him down thinking that he was at a safe bioload. I just wanted to double check and see what you all thought about another addition.
