33 Litre (6-8 gal) Stocking Queries

[Leema]

We've got a 33 litre Jebo (was a bargain at $50).

Though I don't know if the tank has cycled or not (as I don't have any of the test kits except ammonia and pH), I think it has. It has been running for about 6 weeks with three white clouds, 1 zebra danio, 1 leopard danio and a small bristlenosed catfish.

I know the bristlenose won't reach full size in this tank, but he'll be there on algae patrol until we feel that he's reached his maximum size in that tank, where he'll be moved to another, larger tank.

The white clouds and danios will also be moved when we start to put 'permanent residents' in.

We want to put neon tetras and glass catfish in the tank. I know these are rather delicate fish, both of them, so was wondering if anyone has any suggestions on a smooth introduction?

I don't really know how many of each of these to add to the tank. 5 neons, 5 glasses? No idea.
And should I, say, introduce neons, take the danios out and then introduce glasses or whatever?

So the main questions:
How many glasses/neons could I put in this tank?
What should I introduce first - glasses or neons?
Should I take the danios/clouds out before introducing neons or before introducing glasses?
Is there any 'tips' for keeping glasses and neons alive?

Really appreciate any information you're willing to give me on either glasses or neons - or alternatives.
Thanks a lot. Looking forward to your replies.

Congrats on the deal
I wouldn't put glass catfish in a tank that small - they need to be in a group and can get 4" long, they're really suited to a much larger tank.
Neons should be fine, but I don't think a bristlenose is a good idea. Keeping a fish in a small tank can stunt its growth, which affects its health drastically. By the time you decide he's 'reached his maximum size in that tank' the fish may already be stunted. Otos would be my catfish of choice for a small tank. Two otos and five neons would stock that tank fully.
It's best to quarantine new fish before adding them, then once you've established that they're healthy (~30 days of observation) remove any fish that aren't permanent residents (danios/white clouds) and add the new fish to the tank.
