Bioload

[johnyboy]

I have a 75 gallon tank. How many fish can it support. I'm in it for the corals but I love fish too. I'm curious how many fish I can hold??

 

[Reefing Madness]

It would all depend on the size of the adult fish you plan on putting in there, not so much how many.

 

[johnyboy]

I would like blennys tangs sailfin clowns etc

 

[Reefing Madness]

Tangs? As is plural? Your tank would only be big enough for one, as in a Yellow Eye, Yellow, Tomini,Two Spot, Squaretail, Blennys would be fine, Clowns would be fine.

 

[johnyboy]

Yes I only want a yellow tang. What about a sailfin, starfish, wrasse?

 

[johnyboy]

I basically just want to know if I can have a decent amount of fish in my tank

 

[Reefing Madness]

Yellow Tang & Sailfin Tangs require bigger tanks, I'd not put them in there.
But yes, you could have a decent amount of fish in your tank.

What tangs can I put in a 120

The ones listed in bold print. And Im sorry I misseed typed last post, you could keep a Yellow Tang in that tank, my apologies.
The 120 opens up your ability to keep the bigger tangs.

How many u think I can put in in total. And thx

 

[kilo5147]

My tank is 48x24x24

A rule of thumb for me I try to keep only fish that can be expected to grow to no more than 1/3rd the width of the display.
This gives them room to move more freely in all three dimensions rather than having to do laps if the tank it too narrow.

I will admit I have fish that will grow to larger than 1/3rd the width of my current display but I have a 30" wide custom under construction.

 

[Reefing Madness]

AH, I wouldn't put any but the small tangs into that tank, you don't have the length of the tank, you have the height, and they swim back and forth, not up and down.

 

[kilo5147]

Which r smaller

 

[Reefing Madness]

Yellow Eye, Yellow, Tomini,Two Spot, Squaretail, Mimic

IMHO Bio-load is a balancing act in Reeftanks and can be successfully done from one extreme to the other as long as it is balanced. Meaning little LR + a few Fish + few Corals or many Frags/small starts only =BALANCE - to - significant amount of LR or combined live substrate + many Fish + many Coral or mature colonies = BALANCE.

For a 75g Display if given a substantial Live substrate and added volume of large Sump/Fuge with adequate mechanical filtration you can certainly keep and run a fairly high bio-load system. As for the Tangs being housed within I all agree with above comments in a Yellow and Kole/Tomini pair would do fine. IF certain to go larger in future also having otherTangs introduced as small juveniles to grow up with peers can be done.

Pics below of my old 75g DT with high flow 40g refugium and HOB Skimmer. First pic of early in its days and second one about 1 year in and third pic 2 years in which includes three Tangs with a total of 16 or 17 Fish and abundance of Corals. Darn pics loaded in wrong order so 1 & 2 are switched

Cheers, Todd

You could also add White tail bristletooth to the smaller tang list (C. flavicauda).

 

[johnyboy]

Yes rod I have a great 30 gal sump under my 75 gallon and I'm getting a skimmer and all equipment that's needed so I do Believe I can have a bigger bioload

 

[Viracon13]

I have 10 fish in my 75 gallon: foxface, 2 clowns, 2 anthias, 2 dwarf angels, leopard wrasse, midas blenny, mandarin. It's all about adding everything slowly so you give your system time to catch up with the increased bioload. Your feeding schedule will also play a big part in your maintenance

 

[johnyboy]

That sounds perfect.
