Thanks for all replys.
I think Im going to chance it. My r-b-p is only very small but also very aggressive, if i stick him to a healthy diet of meat and greens he should be ok,
I hope...
I will yet you know next week.

Oh I see, Yeah Thanks, for the tips.[/font]

Once a month.!? I feed him bout once a week

i meant feed him FEEDERS only once a month. yea, u should feed him other foods at least once a week. in juvi. stages its usually better to feed them every 2-3 days. but once theyre 5in. or so once a week is perfect.

I also run 2 filtration systems..
A fluval 3+ and a UGF, Plenty of oxygen and water quality is perfect but I seem to can not control this damn algae problem.

I do feed him white fish mostly cod I have gave him ham in the past but not any more. Once a month.!? I feed him bout once a week, He also also eats flake as he is still a juvenial to give him vitamins(aparently) very rare i give him flake and i make sure he eats it all so old flake does not increase ammonia. Nitrates are good.

what "meats" are u feeding this piranha? u should stay away from all mammal and poultry meat. as beef and chicken have WAY to much fat content in them, plus they often have hormones in them as well. stay away from any n all fish meats that are red or pink. cause they are also higher in fats n oils. ur best bet is to go with white meat fishes(tilapia,cod,etc.), raw shrimp, earthworms are good too, but theyre really more mess than theyre worth. and feeder fish should be kept to a minimum, say maybe once every two weeks or month. just to keep that killer instinct sharp.

Then it's probably the nitrAte levels, as a result of the feeding of the meat (presumably raw). More plants and a small water change every few days (for a couple of weeks, see how it goes) should clear it up. You're better remedying the cause of the algae than getting something to fight the problem without the possibility of it ever ceasing. Thumbs up on the larger tank.

Good Luck

I did have 3 but the 1 i have now killed them..
dont worry bout tank im getting a bigger 1 soon. he is only very very small bout 2 inches long in a 3 foot tank on his own.
I dont know what is is causing bad algae. I feed him meet and i watch him eat it all, and i only have light on 7-8 hours a day and no sunlight is any where nere him.
Ph and Kh ,ammonia etc all good. Slightly high Ph 7.9.
Thanks all again.

From what I've heard, the idea with RBP's is to buy 12 - 15 juveniles and allow the faster-growing, stronger individuals to kill-off the weaker ones. This way you end up with a total of 6 - 8 adults (obviously this is just an example) who will happily co-exist with each other. You adjust the number of juveniles up depending on how many adults you want to have in the end (there is a general ratio). This may seem cruel, but its how it would be in the wild. In fact, it's probably more cruel to keep a natural shoaling-fish on its own for the rest of its days. This is most likely the case with your fish. Don't worry though, this can easily be fixed.

I think the pleco and tank-size issues have already been discussed so I won't go there.

Merry Christmas Everyone!

the safer option would be to tackle the algae problem without risking the plec... ie look at what is causing it the algae and prevent it.

I have 1 red belly pirahna about 2 inch's long on its own. In a 100 litre tank.
I have very bad algae, I have tryed all remadies.

Would it be safe to put a common pleco in with the R-B-P.?

plecos can stand up to pirhanas, cuz of their armor-like skin.

but if the pirhana is hungry, yea it can take the plec down

Ooh Where do I sign up for that?

If there was a group of people that slept in a lion's den for the heck of it, would u do it to and think it to be safe?

Yes, but LFS's do stupid things.

my LFS has like 346 plecos with pirhanas, they are fine.

alot depends on the attitude of this particular piranha. but the best way to try this is to get a pleco that is a good amount larger than ur rbp. a single red SHOULD be skittish around another fish that is 3in. or more larger than it. NOW, i will not guarantee ur plecos safety if u try this. my first shoal of reds did just fine with a pleco in their tank. even when they were 10in. they still left it alone, just plain ignored him. my two latter shoals however wouldnt tolerate a pleco once they hit 4in. even when i bought a 10in. pleco, with both shoals they simply ganged up on it. but i do know quite a few people who have plecos with their piranha n all is good. like i said tho, i can not n will not guarantee the safety of ur pleco if u get one. GOOD LUCK

yeah i know that, he is only still a baby, he did have 2 brothers but he killed them. Person at local fish store said it was common when there juvenial's.
I am getting a bigger tank when he is big enough.

I was just wondering how safe a plec would be with R-B-P.? Forget the situation.

I don't think so. Common plecos reach over 45 cm, and will very quickly outgrow that tank. The same goes for the piranha. They reach about 30 cm, and will not fit in the 100 liter tank, either. If you ask me, you should move the piranha, and start over with the tank. They should be kept in groups anyways, and you don't even have room for one.
