Blue/Green chromis/ Stocking help ??

[Jaxs]

Hi everyone,
I have a 70 gallon tank with currently only 6 fish I had more like other fire fish and other cardinals but they killed each other off and now down to 6 and my tank looks so bare. I wanted to add some chromis to liven up the tank but not sure how many to get for best chance of survival. Also nervous my tang will be an butt. Any suggestions as my tank looks really empty.

- Tonini Tang
- Lawn blenny
- Purple fire Fish
- 2 clowns
- Cardinal
- Royal Gramma

Chromis are hard. Their best chance of survival is to be able to eat constantly and have plenty of hiding places. I feel I can keep anything alive, lost a batch of 6 over a 1 1/2 year time span. Plenty of food, hiding places and no visible stress, but still would go down one by one. Even the last one, who would not be shy around any of the other fish, started to do the in corner wall dance. Then it was just a matter of time.
