125 gallons is fine.
125 litres is way too small for pirhanas.
they need the water volume as they are very messy fish...
i have 10 red adults in a 125g and thats all i would put in there as theres just enough room for 10, you really need a bigger tank m8, 125l is fine for a grow out tank though untill you can find them a bigger home. Hope this helps, good luck lee2491;2577989; said:hey,
