what is the easiest fish to breed in a fifty gal?

POSSIBLY
guppies
convicts
white clouds

i have a 150 gal that has always had a constant supply of guppys. i have fish that feed on the guppys but they always reproduce at a good anuff rate to allow predatation and still not let the population die.

Convicts would be really easy to breed in a 150 gallon. They've been described as the "rabbits of the fish world". They are very willing breeders, all you need are one male, one female, and water.

Here is some information about breeding convicts, if you are interested.

zebra danios are such good breeders they're better than mice or rats for genetic experiments...

Kribs kribs kribs kribs kribs!! All racso and I did was set up a 10g (tho a 20 would probably be better) with a grove of thick plants (plastic), a small rock formation, and a terra cotta flower pot on its side. We bought a nice male and female, and let them go at it. Within a couple weeks, fry!

Sexing these fish is increasingly difficult the younger the fish is. Males will have longer more pointed fins with color extending all the way to the end of the fin. This normally isn't the case on females. A strange way to sex these fish which isn't usually the case with other fish is the caudal fin will actually be pointed on males whereas its rounded on the female. Females also have much more intense red/pink on the underside and their bodies are more rounded than the males.

Kribs are interesting, colorful, peaceful, easy to care for, the list goes on... I love them and I think you should consider them. In your case you could have 3 or 4 pairs, as long as each pair could claim a territory in the tank.

Hope that helped and good luck!

I'm pretty sure they're used for genetic experiments because their dna is more similar to that of a human.

"Zebra Danios serve as a common and useful model organism for studies of vertebrate development, because it reproduces very easily, passing from the egg to the larvae stage in less than three days. For genetic research groups, the Zebrafish is an excellent test subject and has already replaced rats and mice in many labs.... If researchers modify its genotype at the egg stage, they can see results on its organs barely three days later aided by the transparency of the embryos."

Livebearers, IME, are the bunnies of the fish world.

Livebearers are easy but Kribs are too, all the really need is a cave of some sort. A flower pot works great, you just enlarge the hole in the bottom, put the saucer on the other end and push it into the substrate. Bingo! BABIES! Lots and lots of babies. Plus they do all the cool Cichlid behavior.

Have fun, Mike

seems we are both correct...

"Zebra danios are popular laboratory animals because of their small size and ease of maintenance. They grow quickly from transparent embryos, which allows scientists to observe test results easily. In addition, their genome is being fully sequenced, and 75% of a zebra danio's genes are identical to a human's."

Kribs would be cool in that size tank.. I have my pair in a 20 gal with Otos and African Butterfly fish..and it's not enough room for a batch of babies to grow.. in a larger tank, with dense planting and caves..etc..you could have enough room for the babies to grow.

Yes Fallout, and they can get thousands of fry from one mating Really easy to use genetic model. I think white mice are more similar to humans genetically, but since zebra danios breed such unbelieveable numbers at once they're often used for genetic research. Of course, that's not necessarily human genetic research. Transgenics experiments with zebra fish also seem quite popular. Take the experiment that produced glofish

75%? Wow.

Some cories (i.e. peppered and green) can be very easy to breed.
Three-line cories aren't supposed to be hard, either.

Just get some guppies that you really like, throw in 2 males and 6/7 females...and close your eyes, turn around three times, and boom you will be over populated...maybe not that fast...but within 3 months you will be going insane:%)heck just get one male and 2 females...they are fast and easy...you get a new batch of fry every 28-30 days...if you are close I'll give you some...time to weed some out I'm afraid...:%)
