I was told to start with few fish and add more later. So I decided to first get some algae-eating fish. There's a bustling cleaning crew in my tank since today... :D (I haven't got any own photos yet, so I link to photos I found on the internet - photos are © their owners)
3 "Pitbulls" (LDA 25 Parotocinclus jumbo)
5 Salt and Pepper Corys (Corydoras paleatus)
3 "Helena"s - the snail eating snails of prey (Anentome helena)
The will clean up so that the Guppies will have a nice, clean home later. ;)
