Rays

[Bugsy]

Can anyone give me some info on the sizes that rays can reach, i'm hoping there is a ray that doesn't get very large )

Thanks

firstly waht size tank have you got there, even the smallest species need a 5ft x 2ft x 2ft and these rays are hard to come bye, all rays are very sensitive to water qualty, i think the smallest species of freshwtaer ray is a histrix ray what has a disc diameter of 12",

Cheers Dany, i've got a 48'x 12'x 15'. Looks like i'm gonna have to keep something else

dont worry theres loads of things you can keep in that tank...what do you like, weired fish? fish that eat other fish, small courful ones? take a pick and ill give you a hand..

Think i'm gonna go for my back up plan of Discus, I used to keep them a while back. Would be nice to grow some on in the hope of getting a breeding pair to keep in the tank on there own

The plan is to get 6-8 Discus, four from one supplier and four from another. After they have grown on a little, say a month or two I will remove two and keep the best looking six. Hopefully as they grow a couple may decide to pair off.....which will leave me with two

Just to clarify the smallest commonly available freshwater ray species is Potamotrygon scobina which attains a disc size of around 12 inches across, P.hysterix is a fairly large species with females capable of reaching around 18 inches across.

How long does it take for a Potamotrygon scobina to reach full size?

Rays dont grow particularly fast with an average growth rate of around 2 to 3 inches a year so a 6 inch specimin should take 2 to 3 years before it is full grown. You "could" keep a pair of scobina in a 4x2x2 tank provided they were the only fish and that the biological filtration was suitably large, a couple of big eheim canisters or a sump would be good, though obviously a larger tank would be much better.

I have a juwel 450 bow fronted tank, and my stock list is in my profile. I have an eheim proffestional 2 filter. Would I be able to keep a scobina?

No, I would say that your tank is basically fully stocked already as you have some potentially large and certainly very messy fish in your tank. If it was me I would have 2 of your Pro2s on the tank.
