Another tank mate suggestion thread...

Severums would be pretty cool. I was honestly considering a little group of em. But clown loaches would be as well. I'm sure they'd help clean up any lingering scraps as well. You guys are giving me some great ideas!

I love the clown loaches and as you say they do a good job of cleaning up the scraps, they eat fish.. prawn.. you name it and have been a good replacement for any catfish that can suck the rays slime coat.They are colourful and active but not in Arowana's face

i know everyone will put in their .02 but small school of exodons with ray have had zero issues. they stay top and ray stays bottom.
