Have the opportunity to get a smaller 8 inch disk motoro ray have a 75 gallon open in the fish room with 3 sponges in it will that be enough it will be the only fish in the tank also how much water should be changed with them and how often ?
Pretty quick also have a 220 open at the moment with plans to build a big plywoodBigger question would be how fast can you upgrade that 75G to a 300G or larger...
pup in a 75 will be good for a bit... 3 sponges is another question all together.. you will have an ammonia spike either way but would need to manage it. Rays produce waste way faster then normal fish and you will need to account for this.. also the sex of the ray will also play into how quickly it grows as females get considerably bigger quicker.Pretty quick also have a 220 open at the moment with plans to build a big plywood

The 220 just seems to big to me for a 6-8 inch rayIm curious, if you already have the 220, why not use that as a grow out and build the plywood tank slowly now???
That extra water volume will be very helpful for water quality. An 8 inch ray still produces a crazy amount of ammonia and waste. They eat an incredible amount of food. Plus you want to move your ray as few times as possible. Rays are known to die of acute stress. Remember, dealing with rays is not like dealing with other fish. Rule #1...bigger is always better when it comes to tank size for raysThe 220 just seems to big to me for a 6-8 inch ray
