In your opinion what would be your best set up for a high school student that wants a South American theme in my 90g?There are many choices of cichlid and your best option for numbers and or diversity is a South American set up. Cichlids that reach around the 6 inch mark. Blue acaras, geophagus red heads, angels, biotadoma cupido are just a few that would be suitable.
If you want to go down the c/a cichlid route, then again I would stay with those that don't get much larger than 6 inches. Thorichtjys like firemouths would work very well in a group of say 8. You could keep fish like sajicas or spilurums.
You could have a pair of jds on their own or a pair of Nicaraguan cichlids.
You could have a pair of Convicts but they can be very territorial while breeding so would greatly limit your choice of tank mates.
It all depends what kind of set up you want. A pair that you can watch breed, a community of fish or one bigger wet pet.
I can advise more of a pricise list if you can explain what type of set up appeals to you most.
Thanks for the help, really appreciate it!We all have different tastes but for me it would be something like a harem of blue acara,a shoal of 15 black widow tetras an ancistrus catfish or one of the other smaller growing plecos and six brochis splendens.
All the fish are fairly Hardy, not overly aggressive and provide a little variety and interest.
