Hi all i was at my lfs the other day and a pacu was in a small tanlk didnt look
to good, i felt sorry for him and bought him hes a black pacu around 12inch . Now iam thinking it was a bad idea he eats everything !! . Will he calm down on the food ?? i do like him and wanna keep him but my rays will always come first .As anybody kept theses 2 together
 
No, pacu will not calm down on the food and are one of the most fast growing fish i know.
They tend to go crazy at feedingtime, so much that I've heard folks who had them had to leave the room after feeding, for the pacu to relax, cuz they tend to get very excited.
Got no expierience on keeping the 2 together, but I'm curious to some of the responses.
 
I personally have never kept the two together but I have seen many public aquarium displays that house the two together. I'm also curious to see what people have to say.
 
Try putting lots of floating pellets in to occupy the pacu, then try the food for the rays. I have the same problem, I got a 16" black three months ago now he is 20" and eats everything and anything( cherry tomatos, dog food, carrots you get the idea) I feed him Koi pellets, they are more affordable.

His appetite will be monster and there are ways to feed both of them but the real issue IMO is that as he grows and eats, your water parameters will be off the charts from all its waste!

personally i wouldent want to keep them unless i had a massive tank and just wanted huge fish to fill it.

it may become a bad idea later on as they eat like crazy and if the ray has what it wants or is close then it may accidently injure the ray. they have powerful jaws that can do real damage as they eat fruit and nuts in the wild if i remember rightly.

plus its going to create a huge amount of waste.

i never buy fish simply because i feel sorry for it, you buy that one then the shop simply gets another and put it in exsactly the same situation. i sometimes thinksome shops do it for that very reason.

yea id get the pacu on like floating food, and at the same time use like a pvc pipe to to the bottom of the tank to feed the rays, so the pacu cant intercept the food as its sinking :)

over time your rays should recognize the pipe as food.
give that a try?
 
these guys eat everything and hoover it up . competition for food later will be a problem i think and trying to feed it enough so there is more for the rays will mean lots of waste . the pacu put things like rtc and tsn to shame imo they grow mega fast .

i dont think agression woudl be a problem as its imo very unlikley they would go for a live food source but due to the size of them and the fact they are so skittish ive heard that they can break glass when they are bigger if they are spooked ( and get spooked easily )

tbh i quite like them but keeping one in any sort of reasonably sized glass aquarium is going to be dificult . either find a way of feeding your other fish seporate to the pacu ( problem ) or deal with the filtration of feeding enough to fill the garbage cans. they really really eat loads.

also . as unlikley as it might be . they are a member of the piranah family and are occasionaly mislabled as pacu when in fact they are carnivourus ( or so i read a couple of years ago )

hope it helps caroline .
