Hi All!
So, I'm cycling my new 20 gal tank so I can upgrade my 10 gal fish to the new 20. I'd like to add another larger fish to be compatible with my female Swordtail but can't figure out what kind that should be! I'll be adding 2 fancy guppies (same sex) as well, if that helps to my Glowfish Tetra, 2 neons, snail, and albino corydora.

Any ideas??? I was thinking another larger fish like the Swordtail just to keep the tank interesting, and maybe the Swordtail won't 'bug' my Cory like she's been doing (though the Cory doesn't look too bothered about it). I've already looked through the Freshwater fish profiles and can't quite decide -- urgh!

Thanks!
~Lenore

I think you should add more cories and tetras to bring their schools up, and let your swordtail be the superstar of the tank.

I agree with Meenu. The tetras and corys are schooling fish which are never truly happy or comfortable when they don't have groups of at least 5 or 6 to keep them company. Live bearers are not schoolers so they would be fine as the only one. Once you up the numbers for your tetras and corys they generally get much more active so your tank should really come to life.

+2 meenu and PP.

Neons especially enjoy safety in numbers. Schools of 5 or more are generally better for them, and IMO, there's something magical about a school of neons swimming 'in formation'

Those are great ideas -- thank you! I think I will do just that!

Can I combine the numbers for the neons and Glowfish, or do I need 5 of each? Ditto on the cories? Do they all have to be albinos (not that I mind, they are beautiful!)...

Do you have glofish (danios) or glowlight tetras?

Sometimes, fish with school with other fish the same size and shape as themselves, sometimes not.

I think they'll school together. Pygmy and regular cories won't school, but cories of the same size should.

I think you'll be fully stocked. Is this what your final stocking list is?
5 cories
8 glowlight and neon tetras (I think you should do more than 5 total of these)
1 snail
1 swordtail
2 guppies

That seems like a lot. How about:
3 cories
5-6 tetras
1 snail
1 swordtail
2 guppies

I really don't want to overstock. I had 2 cories originally and they seemed pretty happy. I never intended to only have 1:-(

do you have the guppies already? The bigger the group, the better the cories do.

what do you think of this?
5 cories
6 tetras
1 snail
1 swordtail

neon tetras produce very little waste, so that should help.

I agree with raising the cories to 5 -- this is better for the cories and more balanced overall.

Yeah, personally, I'd skip the guppies and add more tetras--when they school, it's cool.
