Any aggression from him? They are beautiful but the thought of waking up to some rays with less eyes pushes me away. I imagine a paroon would hold up well, but I'm not sure about jars.I understand, man. Thank you for pointing that out. I am indeed very serious with this build. I already have my fly river turtle (which has been with me for the past 18 years, attached the pic) and my paroon shark. I am going to buy 6 baby jardinis soon and hopefully, them growing together will not be a problem.
