i think it all depends on the Aro's trevor, did your aro initially chase the VATF when introduced ? i know my Aro chased and killed a one of those 10-12" GATF (that Mike brought in) overnight the very first night i introduced the GATF then i was worried to put my same sized VATF in with the Aro, and ya the Aro chased the VATF for 2 days straight before giving up on the chase also the GATF seem to be way more sketish and jumpy compared to the VATF, My GATF most likely smashed himself to death where the VATF can navigate way better in an aquarium!! you VATF looks awesome!!!!
