There are also some wild-type swordtails (Xiphophorous Malinche) that are absolutely stunning in their own way.   

Swords are fairly hardy and very easy to breed. You can easily breed swords by keeping them in hard water and in tropical temperatures.

Also, in an aquarium like the 40-gallon breeder, these fishes will have plenty of space. And you can always include some livestock and rock work for them to hide in.

Shell dwellers are another species of fish that you can put in your 40 Gallon breeder. These fishes have unique personalities. You will constantly be seeing these fish moving the sand around and rearranging the tank.

Most species of shell dwellers are pretty easy to keep, requiring clean water, a pH level of 7.5 or slightly higher, sand substrates, and cargo shells. Species like the Neolamprologus Similis or the Multies are easy to breed.   

These fishes can be very aggressive to any fish that comes in their territory; hence. Your tank mate options are limited.

#4 Rock Dwellers – Lake Tanganyika

Lake Tanganyika Fish

There are other species of rock dwellers like the Neolamprologus Caudopunctatus. Or you can go with Julidochromis Dickfeldi, and these fishes have the same care requirement as the fishes above.

These like to stay in hard water with tropical temperatures. These fishes do get quite lengthy and need a lot of swimming space, hiding spots, and also some rock work.  

It is better to have species only tanks for these fishes.

#6 Goodieds

If you are looking for fishes with a conservative mind, then Goodieds are for you.  

Goodieds are the livebearers and come from Mexico, and these are not the flashiest and most colorful fishes. However, these fishes definitely have some awesome sheens and patterns.

These fishes are extremely threatened in their native environment, and some of them are extinct in the wild.

And you can keep a lot of these fishes in a 29-gallon tank, and there are some species that can live happily in a 45-gallon tank. This makes the 40 Gallon Breeder an excellent tank to breed these fishes.

For Goodieds, the 40 breeder provides a lot of swimming space, better aquascaping ability, and some work in the tank provides better coverage for the eggs.

These fishes like cooler water and suffer if the temperature gets above 75 degrees, so you do not need a thermostat. Also, these fishes need water with a higher pH level, similar to the Swordtails.

Now, if you wish to conserve some species, then Goodieds is the best you can get!
