hi all! I have these two pairs, that I don't have time or space for.... the are all 5" and the more orange one is 6". eggs were fertilized, but in tap water... I saw eggs just go bad. it's a shame. the red map and the red melon are pairs. the other two raflesias are a pair as well. the pairs both laid eggs and were fanning for three days until they got bad. they are very healthy and beautiful. see pics and contact me if interested in getting a pair or two for half the price! :)
