Bio Load Difference

Well the fish would be more. It takes up more room, produces more waste, and requires actual feedings. Inverts are usually smaller and tend to do the tank more good, i.e. clean up waste.

Think about it this way. 5 fish or 5 inverts.... which would take up more? The fish of course.
 
a general rule of thumb. 5g per fish in reef setup.
.
opinions may very. please consult owners manual before operating machinery.
 
Well if you are talking about a 2.5 gallon, then IMO no fish would be good. If you had to get one, a small goby that burrows would be your best bet.

And the fish per gallon rule is just as bad as the watts per gallon. It may work in freshwater, not in salt.
 
yeah damsels are pigs and not only will eat as much as you can throw at it, they'll poop just as much. If you want a fish in a 2.5 gallon, like someone said, get a small citron goby, or for something really cool, get a pistol shrimp and hi-fin goby pair. They're usaully best in a 10 gallon or more, but I think would be fine if they were the only animals in the 2.5 as long as you do a lot of water changes.

definitely ... there are many miniature (baby) gobies!
as you can tell by my sig, I love the mini gobies. One of my dreams is to get like a 240 with tons of live rock and tons of mini gobies to play in the rockwork. They're just so neat because of how they perch and then go in and out of the rockwork. It's like a surprise every time you see them :lol:
 
^ You have 9 fish in a 12g nanocube???

Wow, i thought that I was overstocked with a perc, yellow watchman, and orchid dottyback.

What is your water change regimen and how much nitrate do you have?
 
Wow 9 fish. I thought that I would be pushing my 12 gallon's bioload with a black ocellaris clown and a bicolor blenny.

water change? Is that like changing the oil in your car? j/k yeah I have a very heavy bioload for a 12 gallon, but I'm super diligent on my water changes. I do 2 changes a week of between 1-3 gallons each. Also, I vaccuum out the back chambers of my nanocube where I have live rock once a week as well. Though I'm probably playing with fire, so far, so good (Knock on wood). My setup has been up for exactly one year in August. It's quite amazing how much of a bioload you can put on a tank as long as you do many water changes, enough to compensate for the higher load. Though I am in the process of building a sump/fuge to lessen the need to do such frequent and large changes. If I could get it down to once a week of only about 3 gallon's I'd be stoked.
 
It has to feel to cramped in there for them. Why so many fish?

I am not trying to be mean.... but it is just....so many fish in such a small tank. I mean... even if your water parameters read fine, don't you think 9 fish (a few of them getting over a couple inches) in a 12 gallon is a lot.

And it seems like there would be a downside to doing water changes too often. I persoanlly do not know, but it seems to make sense.
