Do you mean 25-75 ppm (I hope), or 25 dGH? With your pH (quite good) I am suspecting it is 25-75 ppm which is very soft, so I'll go on that assumption.
You could have a lovely setup of dwarf SA cichlids in a 55g with room for "dither fish" like several tetras, corydoras, etc. Possibilities are almost endless. With very soft water (hoping I'm assuming correctly on that
) the pH will begin to drop as the tank matures, over the next 3 or so months. Anywhere in the 6 range will be fine. There are several species in the Apistogramma genus, plus several other genera. Here's a good site for photo index of species: Home
And for info on the species: The Cichlid Room Companion - Main Index
All of these will be under 6 inches, most around 3-4 inches mature. They are usually best in pairs (male/female) and most are easy to sex, with a few exceptions where one male with 2-3 females is better. The info on species will mention this. You could have 3-4 pairs in a 55g. They all like (need) plants, and arrange the plants to provide "territories" so the fish can't see from one to the other territory. Wood is also good in this tank.
Suitable tankmates would be almost any of the smaller shoaling tetras. And corydoras or the smaller catfish species (pleco maxing out at 4 inches for instance), Farlowella, Whiptail species, etc. Just make sure of the temperature requirements. Some of the dwarf cichlids like it warmer (80-82F) and some of the catfish and tetras do not fare well above 78F.
Unfortunately you are not likely to find many of the dwarf cichlids in stores, unless there is a local breeder around. Depending upon where you live, there may be hobbyists and clubs close for enquiries. Of course, there are online fish suppliers, and some of these are very reputable.
Hope this starts you off. This could be a magnificent display. Good luck.
