Fish capacity

How many small fish and reef can I get in a 55 long

 

I guess if you fit them in sideways and stack em....about 10k? Naw here's a fish calculator and remember the little tiny fishies you put in today might grow to be the big ole monsters tomorrow!

LOLOLOL.....LMAO

 

what is the length width and depth of a 55 long?

 

There are a few sizes mines a 55 but is only 3 & half foot long but tall & wide, most are 4 foot, i take it you have not got the tank yet, other wise i would say get out the measureing tape? Haveing said that all 55g should have round the same volume , depending on how much rock or sand, heater, skimmer etc, but based on this you looking at around 12"/14" of fish...but it really depends on what the tank can manage in way of bioload...hope this helps...

 

This all depends on the person, I personaly go by 1" of fish per 5 gals of water. Luna

 

This is my problem with that general rule of thumb, its meant for newbs starting out. The ones who go an buy lionfish, triggers, puffers and all of these other non reef safe fish.

Going by that, if you only put clown gobies in a 55g tank that only get 1.5", that comes out to 9 little clown gobies. Seems like a lot of wasted space considering they dont swim much out in the open and mainly jump around on rocks and corals. But anyways, 55 divided by5g comes out to 11, which means 11 total inches fish. That rules out 90% of tangs right there. Considering most fish get between 3-6"s fully grown, you can have 4 3" fish, 2 6" fish or some combination of that. IMHO, thats a lot of wasted space going by that.


That rule of thumb was made up sometime back in the 70s/80s before all of the newer filtration systems and skimmers and any tank larger then a 55g was almost unheard of or cost way to much money. Now days, all those old school reefers have got rid of their 55g's which is why they are a dime a dozen now but still preach the old general rules.


So yeah, back to the topic at hand. A standard 55g is 48x12x21. you can get away with 1 tang, but research it before you buy it, make sure to find one that stays around 8" or less when adult. Stay away from aggressive fish if you're going reef just because non aggressive fish dont have much room to run from the more agressive ones. I would go with 1" of fish per 2g of water, tangs excluded unless you only had 1 large tang with not much rock.

 

just may not be much room for water, but then you wont have to worry about keeping the parameters in check now will ya.;D;D

 

I got atleast 26" of fish in my 75gal, they've been there a lil' while and seem very happy, just make sure you add them slowly and let water params tell you how much is too much, but be prepared to take something back to LFS and/or increase tank maintanance.
I don't have a true reef tank though i got some shrooms, gorgonian and lil' bit bubble coral.
