Tangs? - Page 2

Reefing Newbie · 07/30/2011, 06:20 PM

I have about 170lbs of LR so from front to back of the tank for swimming room is not extremely open. But I have incorporated a fairly decent sized highway for any tangs added to my tank, it extends the entire 6' of tank.. I am going to add some more rock(I know you are thinking enough) to fill in some open spots that are unsightly and to help fill up more of a corner. Surprisingly the majority of rock is smaller stuff, I may move some of it down to my fuge after I get more rock.

Dont forget, once your corals grow in they will fill in any "unsighltly" spots in your tank. My aquscaping is very open just for this reason.

Could it have something to to with the fact that they are in the fish selling business and not the fish science business? I don't understand this trend of getting fish info from the point of purchase. Why not look it up on fishbase.org or buy a book?

Lol I also found an informative site saying 21" but I think that that is a little too big. Besides, I find a nice mix of reasearch and personal experience is better than one or the other. I am going to say the 9" PBT seems to be more accurate after digging deeper. Also I realize that corals will fill in so I wasn't thing rocks to completely fill, but fix some larger gaps

As Steve already posted, they get up to 21.3 in. Fishbase also says that they are mostly seen about 7.5 in. See fishbase.org I guess Scott Michael decided it was 9.1 based on his experience. His info is not always correct.

If they don't do that in our tanks, there is no reason to assume that it results from anything but something negative. In other words something that is bad for the fish.

One way to look at it is fish should get their biggest in our tanks as food should be plentiful and nutritious and there is no predation. Indeed you see that with many smaller fishes.

Setting all that aside, they are not beginner fish and they shouldn't be put in a new tank - they need a well established, mature tank.

Would I be considered a beginner if I have my tank running a year or more before purchasing the PBT? At which point would you consider yourself able to care for the moderate/difficult fish? I was planning on it being a least a year before a tang will be added, so that would mean I add the kole tang this time next year. I am not sure if take down and setting back up in the same day count as starting over or not. The tank I have was 1.5 years old when I got it. It is currently on day 7 of my possesion with no ammonia or nitrite detectable. There is hair algae, brown algae, and lots of coraline algae present. Brown algae is only there as I had light running for 12 hours per day, but that has been cut back to 6 hours for now. Will be trying to get the daylight bulbs going for 9 hours while acintics run for 11 to ease into the day like sun up/down. Need to pick up a timer.

That's a really good question and I guess the answer depends on the individual. That you are planning to wait a year says a lot about your dedication. However, I also think the 125g recommendation is too low. To me, a 7 in. fish swimming around in there will look cramped and make the tank look small. Especially since tangs aren't especially bendy.

Reefing Newbie · 07/30/2011, 10:33 PM

That is true, but as far as the tank size I am going by RC as they have the most reasonable tank sizes listed compared to most books/sites. This being my first reef tank, I am dedicated to having run as problem free as I can. Slow is how it goes from what I have been told. The tank won't be messed around with much now that I got the aquascaping issue out of the way(corals dictated rock placement too much, the rocks weren't secure). Messing with the tank's natural balance leads to trouble at some point. Learned that with freshwater, but now I am breeding various fish there. I am trying to also keep in mind that this tank may or may not be up and runnig for much more than 3 or 4 years. Not sure if I will be able to take it to college or not. Would be one heck of a move! If it does not go to college with me the tank will have all inhabitents taken to the lfs, but the tank will be running with the water and LR to keep it living for my next setup. At my lfs's price for live rock, there is over $1k in the rock alone! I think I will see how I feel when a year has passed about the PBT, who knows something else may have caught my eye instead.
