interestingly he said i could have a couple of electric blue rams when my tank has mantured maybe 2 months down the line because the ones he gets are used to London water. he even had them mate!!!
Yes, this is possible from the water parameter perspective because this species (
Mikrogeophagus ramirezi) does best in water with similar parameters to that in which it was hatched and raised. However, it does need warmth, 26-7C/80F absolute minimum, but this will not bother your Endlers [
Poecilia (Acanthophacelus) wingei] so that is OK, but I mention it as some do not understand the need for warmth and the rams do not live as long as they could normally. Tank size may be an issue, from the info that essjay posted earlier. If a larger tank is possible as you mentioned in this thread, that would be better.
At this point so it is covered, I will just mention something about this blue ram fish. If you want a pair, they must select each other and bond, or one will likely be dead before too long. This applies to most cichlids. You can usually discern a bonded pair from carefully observing the behaviours of the fish in the store tank for a period of time. Males will be continually "charging" each other, so that is easy; females will usually be just sort of hovering around, picking at stuff on the substrate, generally minding their own business. If a male allows one of the females to remain close without any pushing, that "pair" should bee successful together. But nothing is cut in stone, and sometimes even this bond can fall apart in a different environment.
Earlier shell dwellers were mentioned...these are not "community" fish so in a tank on their own, fine, but not with the other fish now being considered.
You also asked about plants...CO2 is not needed and certainly not for the plants in the photo in post #1.
