– Keep Your Red Hook Silver Dollars in a School of Six or More

Red Hook Silver Dollars are schooling fish. This classification means that they always move as a group with members of the same species. An ideal school size for this type of fish would range from at least six to ten Red Hook Silver Dollars in one aquarium.

– Provide Them With Enough Space for Shoaling

Aside from being a schooling fish, Red Hook Silver Dollars also exhibit shoaling behavior. Shoaling fish stay together for security and sometimes for establishing a pecking order — fish like these need to be in a long tank with a capacity of at least 125 gallons.

– Avoid Using Them as Dither Fish for Aggressive Species

Red Hook Silver Dollars make for excellent dither fish due to their calm nature. They are almost always out in the open. This, in turn, encourages shyer members of a community tank to come out and interact with others as well.

However, you should avoid using them as dither fish that are meant to distract the more aggressive species in your tank. It will only stress out your Red Hook Silver Dollars and make them prone to illnesses.

The Best Tank Mates for Your Red Hook Silver Dollars

The best tankmates for silver dollars are usually bottom feeders or peaceful upper and mid-water level fish like catfish, placid tetras, and loaches.

Below are some examples of fish that would make excellent neighbors for your Red Hook Silver Dollars.

Plecostomus

Called plecos for short, these fish are bottom feeders that are not only peaceful neighbors but also excellent housekeepers.

Catfish

Like plecos, these fish thrive at the bottom level of your tank. They are not usually aggressive, and they tend to do well in moderately planted tanks with a rich substrate.

– Loaches

Loaches are colorful scavengers. They are not overly territorial, and they mind their own business most of the time.

You might also want to pair your silver dollars with other docile tetras that are not too small in size. You can even introduce Red Hook Silver Dollars to tanks with cichlids, provided that the cichlids you have are non-aggressive and are of almost the same size as your silver dollars.

Breeding Red Hook Silver Dollars With Ease

You can quickly breed more of your wonderful Red Hook Silver Dollars by planning and making the necessary preparations.

Read on to learn how to prepare for a successful breeding season for this particular fish.

– Prepare a Separate, Planted Tank for Your Breeders

While the breeding tank usually is smaller than your fish’s community tank, it should still have superb water quality to make for ideal breeding conditions.

In this case, you want to keep your water soft at about 8dH or less. You should also maintain the tank’s temperature between 80 and 82 degrees Fahrenheit. Keep the tank under low light settings with a heavy volume of fauna towards the middle and bottom layers.

– Select a Healthy and Dedicated Breeding Pair

The ideal Red Hook Silver Dollar breeding pair will have a male determinedly chasing its desired female. Both males and females should be healthy and have a good appetite.

– Leave the Breeding Pair in Their Tank and Wait for Eggs to Appear

Keep the tank dimly lit at this stage of the breeding process. Shortly after a successful mating, the female should be able to release thousands of scattered eggs throughout the tank. This is where the plants at the middle and bottom layers of your tank will come in handy. They will serve as nesting grounds for the eggs until they hatch.

Aid the Fish Fry for a Few Months Before Releasing Them Into The Community Tank
The eggs should hatch after three to four days in the breeding tank.

Keep the newly hatched fish fry in the breeding tank. Monitor them and supplement their growth with fish fry food. You can release them into the community tank after a few months or before reaching maturity at eight months of age.
