Not to discount anyones experiences, but everyone contributing in this discussion (for the most part) but Balton has 1-3" fish (and Im sure some with bigger ones will chime in). As we all know, there is absolutely no way of judging the outgoing-ness of a fish at that size, so I wouldnt say thats an indicator of anything. Fish that small dont know much about self preservation, just like an infant doesnt. Its estimated that only 1% of a spawn make it to be a juvenile and less to an adult.
Id also say that if you read all the experiences from large festae owners who have posted their fish/experiences online, 85-95% have the same experiences Ive had...and their posts will attest to that. They are (or usually always have been) just skittish fish....and nowhere near the personality of Oscars, Trimacs or Midas/ Labiatus. Not saying they should be, just saying youll more than likely never get one to let you pet it, hand feed it..like REALLY hand feed it, not stick in fingers and have him take food so fast you cant tell if he got it or not or sit there and follow you around the room like the aforementioned fish. Now, Balton says his male is interactive, so maybe they will get that way above 10". I dont know, but I havent kept one to that size or read of others with them that act as such at bigger sizes.
Now,was my experience because there were way less farm bred/tank raised festae over the past 10 yrs than there are now and that the wild caught aspect has anything to do with their personalities? Id say so, but Im no Ichthyologist or animal husbandry expert so I couldnt say with any knowledge behind that, only common sense.
Ive kept them in communities , in differing sizes, in 75g, 125g, 180g & 265g's. Had them from fry to 10", singles, pairs and the last pair I had spawned a lot then one day the male just killed the female.
My last pair also had the 265g to themselves which I think was part of the problem. They had too many places to hide. This was their tank:
about the avatar..haha. I was gonna animate this one but Ive just been busy with work and trying to finagle things to try and get a new paludarium going, if I can.
