It's a 20g un-planted tank with the following fish in it:

5 Tequila Sunrise Guppies
3 Cories
2 Dwarf Gouramies

I want to add a school of neons (or cardinals...if i can find them). How many do you think i could safely get away with?
 
I don't have any significant experience with neons (not a big fan of tetras, sorry). Just a warning to watch your two dwarf gouramis- they are most likely both male. Also, for brevity, you could just say 5 guppies instead of "5 tequila sunrise guppies." It's like differentiating between a crowntail betta and a doubletail betta- different looking, but still, a betta is a betta. :)

I would probably hold off with the neons though. Guppies have a funny way of multiplying. Unless of course you have only males.

Also, for clarity's sake, what kind of cories? Bronze cories, for example, get a lot bigger than julii cories. That will affect the bioload significantly.
 
Probably about 6-8 - but only if you don't keep any of the fry from the guppies. Though I am sure the gouramis would be more than willing to help in that department;)

Just make sure that you have a LOT of plants to help keep the gouramis happy:) If they have somewhere to go where they cannot see eachother, things will work better. Not all males will fight, their personalities vary from fish to fish. I have 2 males in a 10g now with no problems (at one point 3) but I have also had males that thought they were bettas and had decided that the other fish must go;) Just pay attention closely.

I can't help but mention...aquarius, you're telling them not to specify their guppies for brevity's sake, but to specify their other fish for clarity's sake? LOL. I understand that cories can be bigger depending on their kind, but I see nothing wrong with him telling us what kind of guppies he has.

Leopardess, nothing wrong with spelling out Tequila sunrise guppies, but not necessary either. They're just like regular guppies except with pretty yellow and orange tails. It's all the same species (unlike with the cories). I mean, this forum does other things that shorten posts (LFS, HOB, etc). Just trying to help out word economy.

But feel free saying sunrise tequila guppies if it makes ya happy. :D
 
LOL It's okay:) I know what you were saying, I just thought it was kind of funny on a superficial level. Keeping brevity while maintaining clarity:)
 
It's the first time i've mentioned the guppies here...so i thought i'd say the full name. :p All the guppies are males...so no fry. I'm PRETTY sure both the gourami's are male...but not 100%.

I believe the cories are Peppered Cories.

I also just added a new rock, and a few plants...and re-arrainged the whole tank, so there's tons of hiding places.

Here's a pic. I'm quite proud of how it all came out. :D

If you spot the swordtail and the serpae tetra in there...they arent there anymore, I gave them to my g/f. :cool:
 
heres a little formula for finding out how many fish can be in your tank.

take the surface area of your tank( length times width), then divide that number by twelve for tropical freshwater, and that is the max inches of fish you can safely have in your tank.

The reason that the inche of fish to gallon formula doesnt work is because surface area determines the amount of oxygen that dissolves in the water.


so for example. My ten gallon tank has a length of 20 in, and a width of 10. So multiply 20 and 10 and you get 200, divide that by twelve and you get 16.999999999 rounded out thats about seventeen inches.

all freshwater fish need about 12 sq in of space
all coldwater need27 sq in
and all marine need 47 sq in

sertain fish though, like anabantids(gouramis and siamese fighter fish) can live in low oxygen conditions. The reason for this is that they have an auxillary breathing organ called a labyrinth. thats why siamese fighters can live in small cups and such.
 
I have a fairly large bubble wand in there too...wouldnt that help with the oxygen?

The tank is also roughly 23"x12"
