Question
I HAVE 4 PACU IN A 150 GAL. THEY SEEM TO BE MORE AGGRESSIVE WITH EACH OTHER AND ARE ALL HANGING AROUND THE BOTTOM OF THE AQUARIUM. THEY ALSO SEEM TO BE DARK GREY. DO YOU THINK THEY ARE SICK OR NEED SOMETHING? I REALLY APPRECIATE YOUR HELP!

Answer
Hi Mashelle,
Usually, Pacu's are not aggressive. If they are grey in colour this is a sign of stress due to bad water quality.
Test your water for ammonia, nitrite and nitrate. Daily water changes may also help. The dark grey can also be caused by bullying. Keep an eye out to see if one of them are being bullied.

Regards,
Chloe.
