how many fish

[Andrew G]

I currently have 14 small fish in a 15 gal with an Aqua Clear 20. Can I add more fish if I install a second filter, such as an Aqua clear 30?

That depends on what kind of fish they are and how big they will get.

I want to add 3 more Neons and possible one more cory cat

What is in there already? And what are the size of them?

15 gal with:
5 White Skirt Tetras (1.5 in)
4 Black Neons (1.5 in)
3 Neon Tetras (.5 in)
2 Cory Cats (1 in)

You are really stocked to the limit, what filter do you use as if you over stock abit best to have a back up filter,neon tetra's are not big waste producers, so maybe get 3 neon tetra's and 3 black neons so they are in a shoal of six.

I wouldn't recommend adding anymore to the tank. You are already at 17 inches, with a 15 gallon tank. That is over already, even though you have a larger filter. It's more about the size of the tank, than the filter rating.

I would say you could add a few more cories. These are schooling fish, and would do alot better if kept in a larger group. You could also might be able to get away with maybe 2 more neons and another black, just to give them a bigger school.

Neons are very thin fish, who are also light waste producers, so you can probably pus the inch of fish per gal rule a little.

Whatever you do, add these new fish slowly, and monitor your ammonia and nitrites to make sure you don't have a mini cycle.

Sorry for being a little off topic but...
If you have an extra 15 gallon, connect the two
It's really easy to make, just use pvc pipe. You could add so much more fish, and it would be cool. Just need a larger filter.

How do you connect the 2. I'm not sure what you're talking about

I sent you a PM.

I reckon you could get away with more, so long as you add them gradually and use an extra filter. In fact if you stick to 3 more neons and 1 more cory you may be able to add them all at once, but please monitor water quality. I have a 13 similar fish in a smaller (planted) tank with a large capacity (though not over-powered) filter and barely register any nitrates let alone ammonia or nitrites. Maybe the type of cory would make a difference. Mine are pandas and so are tiny!
