Right now I have a 30g tank and I want to get about 5 1" rbp's. I have a power filter (200gph) and a powerhead on it. Will this be enough filtration for it? It's working fine now for my 20 small, hardy fish that are in there (livebarrars and barbs) now, but I heard piranhas are very dirty/wasteful fish.

P.S. I'm going to give those fish to my sister when i move though so I can get some rbp's

5 p's will outgrow a 30 in 2 or 3 mos. And yes the are dirty. Because of the food.

With 5 in a 30 (they will not be able to stay in a 30 very long) you need more then 200 GPH filtration. Most people try to get 10X turnover or 300 GPH.

The p's are going to be in it less than 4 months. I am planning on getting at leat a 100g when I move

Hope you can provide your Ps with a bigger tank before 4 months. In their juvenile stage, Ps can grow an inch every month (very fast for the first 5 months), and your 30 gal will be too over crowded. Within 2 months, your babies will be fighting for space and territory (if not already) and will result in a loss.
