Answer 1

DIET: These guys will eat all sorts of stuff. In the wild they eat algae, plankton and small insects. In captivity they will take just about anything including flakes, bloodworms, tubifex and shrimp among other things.

TANK REQUIREMENTS: These fish are used in toxicity studies so it should come to no surprise that they are hardy. The tank will not need heat of any kind, decorate the tank with plants and caves. I recommend at least a 10g for a couple pairs. For breeding a sponge filter works well, or something else that will not suck up the eggs/fry. A bit of filter floss attached to the intake on a HOB will work. For spawning caves use slate or small PVC pipe (4” diameter cut in half) to make some cave


BREEDING: This is the interesting part, many people think these fish merely scatter their eggs around, this is not true, and their breeding is far more complex. To induce spawning all you really have to do is provide a 16 hour photo-period with 8 hours of darkness, this with a good diet of things like bloodworms, brine shrimp and daphnia is all it really takes. When ready to breed the males will develop a spongy pad around their head (hence the name fathead) with breeding tubercles on top. These tubercles look like small white bumps or pimples. He will also turn dark in color, almost completely black. The male will then stake out a territory. He will defend the cave and try to attract a female with the use of pheromones. He will also dance in a figure eight pattern. Once a female decides she wants to spawn with him he will lead her into the cave where they will spawn on the roof of the cave. Sometimes more than one female will spawn with a male. The male will care for the eggs, rubbing them with his spongy nape and snout in order to keep them clean. Spawning usually occurs in the morning.

THE EGGS AND FRY: What you choose to do with these is up to you, chances are the success rate will be higher is you move the eggs to another tank and place them next to an air stone. You can also keep them with the male but remove the others and remove him after they hatch. The young can be fed Artemia nauplii, Hikari first bites (or other baby fish food) and finely ground flake

Goldfish are very demanding to reproduce in a small tank. A pind might want to probable be a much better decision or a huge indoor tank for hotter goldfish. i might want to point to discover yet another type of fish to reproduce alongside with Cherry Barb because cherry barbs are almost extinct contained in the wild.
