Like you say, A. gephyra and A. pertensis are often imported together, along with A. gibbiceps. I've had all three in a 250-litre tank (125x45 cm surface) or 66 gal (49x18 in) for you non-metric guys. I had 2 pairs/1 "trio" with no problems at all. A 30g should be enough for A. gephyra/A. pertensis as I don't consider either of them to be very aggressive and/or claiming very large territories (sp?). Part of the fun is actually keeping different species together and watching them "interact", fighting for space and tending their fry. Good luck Fredrik L.
