I have a 20 gallon tank that is like two ten gallon tanks. Could I keep a Afracan Giant milli with a crestie in this tank? I wil be using the Gravle Bottom set up, the milli is for clean up duty. I NEED AN ANSWER SOON! Thanks
Housing two different species in the same tank is never a good idea and should be avoided at all costs. My guess is the crestie will become stressed just being in the presence of the milli, which would probably cause health issues. I would highly recommend keeping them in two separate enclosures.
