The angel fish probably won't make it through the entire cycle
I have 3 gulpers ub with a wolf fish silver arow and 3 sting ray
Without any problems. I
Some of these Gulpers are very lazy, if i remember correctly, i think i read of people having them with goldfish, that were feeders, they didnt eat. Dont know if this is true tho.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.
