unhappy with my tropical tank

[Henry_VCG_]

Can I add more fish to My 70 litre tropical tank (in sig)? If so what should I get? I am going to rid the tank of the bully (give it back to LFS) it's a community tank and I would really like some new colourful fish. Any advice would be greatly appreciated

Forgot to mention I have a rather agressive head light and a head and tail light

It's hard to tell from your signature. How many baby platy's are 'a lot'? The general rule is 1" of fish per gallon of water, Tho I've also heard that for fish over 5" it should be 1" of fish per 5 gallons of water.

Some fish are not suited for a 20 Gal/ 70L tank no matter what (I gave away my blue gouramis today because they needed at least 30 gal and 36" of swimming room ).

Is your catfish a Corydora? If so they like to be in groups of at least 3. I had one and he was all sad and morose, then I added 3 more and they are all swimming and playing together.
