180 gallon tanks for rays?

  • We are currently upgrading MFK. thanks! -neo
Either a retic or a hystrix will be fine in that tank. Hystrix are hardier and IMO they look better, but also a little pricier

Sure give it a try. Retics are hard to get eating but as long as you have a stable system with good filtration then they should be fine. Just do not get discouraged if you have one die on you at first because it could easily happen. They should live in that tank for many years. If their tail and front of disk can touch the front and back glass at the same time then upgrade.
 
The blackpo looks like a Leo but this is believed to be a scam so be careful. Retics are cheap but often die when young. Hystrix would be good if you can find one. Also some male mm (marbles) seem to stay small.
