Herotilapia Multispinosa - Juwel Rio 180

[JanCichlid]

After 2 years without a tank, I recently started with a new one.
A Juwel RIO 180 (180 liter/47,5gallon), set up with some plants, leaves, stones, wood and sand.
Couple Herotilapia Multispinosa (Rainbow Cichlid) and 12x Hyphessobrycon Erythrostigma (Bleeding Heart Tetra).
I replaced the internal filterpump, which only had 158gallon volume, to a 264gallon pump.
Currently im using T5 lightning but the LED lightning is ordered and will arrive next week.
Im also monitoring my tank with a Seneye Home Kit.

I would like to add some more fish, but I have no idea which fish yet. So any suggestions are welcome.
Im also trying to figure out which camera settings for my dslr are the best to take pictures.

I have a breeding pair of rainbows in a 40 breeder and I'm really reluctant to keep much of anything besides Cory's with them. My male is the most aggressive fish I have ever owned and since they breed often, it's not a good idea to keep much in the tank. If you do put something community based in your tank, just make sure it's fast. I have rosy tetras and I wouldn't put them with my fish because they'd be dead in no time. danios and Denison's barbs work great with my convict and I'm sure they would work with your setup.
