help with p's

[daveg]

i tried introducing 5 new smaller rbp's to my tank which is 300l not sure how many gallons, i already had two rapidly growing p's now about 3 1/2 long all went missing in action! two i belive to be sucked up by the ehiem (must get gaurd) but the others eaten, do i have to get the same size p's as my own or is there a method to do this?
previous i had 12 rbp's and ended up with 10 good uns but had to sell on due to my move.

i also have a corydoras thats quite happily living with the p,s will he likely to be destroyed at some point?

can the two p,s share with a black piranha? need some tank mates for the lads.

and are catfish pellets ok for the p's as they seem to like them?

cheers for the help, sorry for the ignorance.

Hiya daveg, welcome to MFK, I have kept redbellies and wimple's but never blacks, so others might have different answers. This are my opinions.
it is best to get piranha as close in size to each other as you can until they are over 6" long, once they are that size they can be kept with larger ones. When adding rpbs to an established tank pull out all the fish into buckets for an hour or to and rearrange the tank, adding a few bunches of plants as a visual break won't hurt. then put in all the fish at once, it will put them out of feeding mode for a while and the rearrangement will make all the fish feel like new fish so the real new ones are not as likely to get singled out as prey.

I have never successfully kept any fish with rpbs for any real length of time, even corys and plecos get eaten sooner or later.

Black piranha are serrasalmus species and they don't shoal, either the rpb's will eat it or more likely vice versa.

Catfish pellets, other fishfood pellets, and pieces of fresh market fish and raw shrimp/prawns, and clams all work. I prefer to serve a mixed diet, and also include live food but I understand that is a luxory in the UK. Mixing types of food helps to make sure they don't end up with an unbalanced diet.

Good luck!

Dave hi mate !

300L is 80Gal

You say that you may think that you 3.5" piranhas may have been sucked up by your EHEIM Highly unlikley ! they have possably been eaten by our other piranhas.

Also your corys will more than likley become a meal too at some point ! the way to seperate piranha is like Guppy said you need to get them all of similar size because they are highly canibalistic they will eat anything smaller or injured and if in a good size group anything larger than them selves. if i was youy a would look for piranha of the same size to add ro your aquaria!

The black piranha isn't a shoaling fish like a Pygocentrus nattereri the black piranha serrasalmus is ( Like guppy said ) a free swimming fish and is naturally a larger growing fish and MORE AGRESSIVE so i wouldn't advise you to mix the two speices!

Keep pygos with other pygos. As for size the new ps have to be close to the size of the original you already have. I had 5" rbps housed with 9" rbps and had no conflict of any kind.

Like everyone says on pfury piranha cohabitation between serras and pygos almost never work.
