Change of Fish after my disaster

[hikingboots]

Hi all i'm new to the web site. I am from Ireland, my tank is an 80 litre plasma tank, i had African cichlids in the tank for nearly four years it was a safe and happy place or at least i thought it was... I went away for a weekend middle of september came home to find all my fish dead i was stunned done all the water checks they were perfect then i put my hand on the outside of the tank and got a shock literally had an electric fault my poor fish got poached over the weekend. My tank is sorted and now i'm ready to go again, i put danios in it from a small tank i had and now i feel guilty taking them out so i now need advice on the type of fish i can put in with them. Have ten danios and three small pleco in the tank now about two week's they are all doing well so i want to put more in any advice more than welcome.
Cheers for now.
