Seems like a fairly easy question to answer: most seasoned vets (even I) suggest and use the standard 29 gallon (30″ x 12″ x 18″). However, the 20 gallon highs (24″ x 12″ x 16″) will work fine as well. But let’s take a further look into why the 29 gallon is deemed the best:
HEIGHT vs. WIDTH vs. DEPTH:
In my experience, the tank needs to be at least 24″ wide and 12″ deep so it gives the discus pair some room to swim around and engage each other. However, I also found that any tank not being tall enough will not motivate Order Generic Levitra Professional Online without Prescription discus to spawn. If your breeding cone is almost coming out the water or you only have about 3-4″ clearance from the cone’s tip to the water surface; many times the discus will not breed.
I could never get mine to breed in a 20 gallon long (30″ x 12″ x 12″), but as soon as I got them into a 20 gallon tall, they would start laying eggs like crazy. So my suggestion is have a minimum of 16″ in height.
So the tank dimensions cheap generic cialis of (24″ x 12″ x 16″) (20 gallon high) will work as an absolute minimum footage size for discus fish breeding pairs.
FOR FRY:
With anything bigger than a 29 gallon, your fry are going to work harder to find the parents once they go into free swimming stage. They need to attach and stay with the parents for the slim coat within 24-36 hours; it is pretty crucial this happens.
With anything smaller than a 29 gallon, your fry won’t have much room to grow. Of course, if you artificially raise the eggs, you can get away with this. But for the most part, if you let the parents raise the fry for the first month, then the fry will get about dime size before they need to move into their own grow out tank. Imagine 50+ fry plus the parents swimming around for a month in a 20 gallon aquarium. That extra 9-10 gallons will make a difference.
Hope that helps and good luck!
