Room for one (?) more species...suggestions?

[Danny-O]

Newbie, looking for sage advice! :bowing:

I have a 33g tank (standard rectangle, 12x36" top)
Started Jan 1; fully cycled.
20% water change weekly
Lightly planted, though more planned.
pH 7.6; nitrates running 10 between water changes.

So far, I have:

7 zebra danios (action)
6 neon tetras (sparkle)
3 black kuhli loaches (comic relief)
1 ghost shrimp (keeps the floors clean)

I'd like to think I have space for one more smaller fish, one that doesn't mind being alone and will behave himself among the neons.

I'm favoring a dwarf gourami at the moment.

Or maybe I should add in the obligatory team of otos and be done? I don't have much algae yet, though it's coming.

What do you think? Any other suggestions?

platies are fun. pretty active fish, and brightly colored. You will want 2-3 females per male though, the males always want to breed, and that will stress out a female. The more females you have per male, the better, give him more females to bother

Guppies are a good choice as well, however, if you have other livebearers in the tank, limit how many you have. I am having a problem right now with my guppies (i have 7, all male) trying to mate with my female mollies, of which I have four (very weird, btw to see this), so I installed a tank divider today until I get my 20 gallon tank on wed.

BTW: I have a 55 gallon with 10 zebra danios, 10 neon tetras, 7 guppies, 6 black neons (going to be 10 once the guppies get there own tank), 6 mollies, 4 harlequin rasboras, 3 silver hatchet fish, 3 lemon tetras, 1 clown loach, 1 ghost shrimp. my system is very stable, 0 ammonia, 0 nitrite, 30 nitrate, 7.4 ph, 78* F. Has been at those parameters for the past three weeks with no spikes. Nitrate decreased from 40ppm last week to 30 this week.
