the only trouble i would see with going from a 125 to a 180 is the price jump. I think its around a 150 dfference. I am about to order there 120 ( 4x2x2) or my teacup/ chcilids.
Eric L said:I just checked glasscages.com man and I dont know what kind of space you have man but a 96x24x24 240 gallon tank from them is only $20 more than a 48 x 48 x 13. I dont know what kind of space you have but if you want to keep small species of rays I think that tank would be better and you could keep more, maybe 2 or 3.
HA pearls and black rays are almost unheard of in the us nowtyson said:Hi there
You want to get a ray which has better resale value & pleasing on the eyes.
If stocks are available & within your price range, get a PDR / Black ray
