Gulper will without a DOUBT eat the angels. They look like veils to me which means they're even slower than regular angels. Gulper will just wait until they get close then say goodbye to them. Some people may have more docile ones that will put up with tankmates but if I were you I'd just do 2 gulper so with no other tankmates.
Do you think two would be okay in a 50? That would be awesome. Im planning on keeping just one. But if two can live comfortably in a 50 then id take a shot hehe
