90L what else?

[GoldenPlecTony]

Hey guys,

I have a 90L tank and want to add some more fish. I have 6 Neons, 2 Mollies (Male died), 1 Danio (inherited), 4 Corys, 1 Synodontis (Soon to be rehomed) and 1 Betta.

Is there anything else I can add in my 90L long tank? 2 Filters running in it with 2 plants and 3 plastic and a sand bottom.

I currently have a fungus in the tank on the neons, they have little white ball's on their mouths so im treating and I want rid of that before I add so I have plenty of time to decide.

Thanks

Ps I have a tank at work which is about 250L... This has a common pleco, 6 neons, 6 Danios, 6 Tiger barbs and 2 platys.

Am I right in thinking my fighting fish would be killed in this tank? Maybe the Tigers would gang up on him?

Just mentioning I have the possibility to chop and change where the fish are held so the options are greater for fish additions.
