hey all i am currently running a 300 gallon 3x3x6 roughly tank with a 50 gallon sump and i have it stocked with one male motoro (~9" disc) a pair of marble rays (~6" disc) 2 8" O's and a a couple common pleco's i was wondering what kind of tank mates you would recommend to go with these guys. i was looking at maybe some kind of other central american/ south american cichlid or possibly something like a peacock bass. my next upgrade is a larger sump and then a large uv sterilizer ( the little one i had worked great when the rays where in my 100 gal)

pics to come
also thanks in advance
 
What we don’t give credit to the guy who got ya the tank anymore? ;) I’d ditch the plecos you always here bad thing about plecos and rays then scoop maybe a few pbass or a nice Asian Aro? There’s a guy local to me (near Newmarket) selling his Asian aro 20” for a great price. Meet me in Sudbury I could bring it up for ya
 
Also for a sump upgrade. I got a custom JT acrylics sump you may be interested in as well as a new vectra m1 return pump
 
The Motoro to the left in the photo. Is its left eye okay? Looks very cloudy, maybe just the picture?

Yah the motoro’s eyes are a couldy I’m not to sure why tho. I did just get back from vacation so I suppose the person I had watching them might not of changed the filter floss of over fed but he has had eyes like that for a while. The other rays eyes are clear and the tank has a 50-75g/day drip and overflow system plus I drain and add additional water about every 2-3 days ~30-60 gallons

So not to sure what’s going on if you have any ideas that would be great
 
Stingrays are fairly tough, but their eyes are especially sensitive to water quality. My guess is your helpers overfed and/or skimped on maintenance while you were away which is extremely common. You probably have some ammonia and nitrite in your system. Test you water for ammonia, nitrite, nitrate. Wouldn't hurt to do kh/gh/ph also.

Could be from injury, but it doesn't look ruptured or swollen, which leans me toward possibly just ammonia burned. Which should recover fully if fixed quickly enough. If you don't have a test kit I think you should consider some extra water changes to dilute any waste that could have built up in your system over time. As this is a likely culprit or factor.

Let's see the other eye? Any other fish with cloudy eyes?
