What is a compatibility chart?

A compatibility chart is simply a table with a list of fish, invertebrates, or plants on both axes or sides of the chart.

The method of ranking varies but usually includes Compatible, Incompatible, and Maybe.

Do small goldfish fit in a small aquarium?

Why do fish have different sex hormones?

That gene only “switches on” in the presence of estrogen, a female sex hormone. “When we find vitellogenin in the blood it’s a pretty clear indication that those male fish were exposed to extra estrogens of some kind,” says Iwanowicz. One environmental estrogen is ethinyl estradiol—a chemical found in birth control pills.

The sex is not determined by different genes, but by the environment impacting the activity of these genes. Similar mechanisms regulate adult sex change in fish, so this may be important in translating the social cue into molecular action. Surprisingly, we saw the turn-on of some powerful genes that are active in embryos and stem cells.

How does stress affect the reproductive function of fish?

High levels of the stress hormone cortisol are associated with temperature-based sex determination in other fish and reptiles. Cortisol probably alters reproductive function by impacting sex hormone levels. Stress could be the unifying mechanism that channels environmental information into a change in sex.

What causes stress in a fish tank?

The primary rule to remember with stress is that, as the saying goes, prevention is better than cure. The things that cause stress in a fish’s life (“stressors”) include overcrowding, handling, a poor or unfavorable environment, inappropriate or aggressive fish sharing the same tank and, in the wild, predators.

What are the reproductive systems in fishes?

In this article we will discuss about the reproductive systems in fishes. The reproduction in fishes is bisexual, hermaphrodite or parthenogenic. The most predominating process is bisexual reproduction. In such fishes the sexes are separate, e.g., the individuals are dioecious.

How does stress affect reproductive fitness in fish?

Taken together, the allostatic load due to stress appears to reduce reproductive fitness in fish (Schreck, 2000). This can be manifested directly in reduced survivorship of the adult or via reproductive failure. Reproductive impacts can be attributable to effects on maturation, time of spawning (or ovulation), gamete quality, and progeny quality.

How does a fish become a female?

If the fish is to become a female, then the reproductive organs produce fish eggs – as well as other hormones that cause the fish to behave, look, and function as a female. In males, the reproductive organs produce sperm cells – and the fish begins to behave, function, and appear as males do.

Can fish change sex?

A human is born one sex or the other depending on the chromosomes inherited from the parents. Even a surgical sex change, can’t enable a man to produce eggs or a woman to produce sperm. But several kinds of fish not only can change sex, but do so as part of their normal reproductive cycles…

How does the fish’s inside change?

The fish’s inside change because of hormonal reactions. These changes in the relative neuronal activity in the male brain transmit along the hypothalamic-pituitary-gonadal axis. Then, the brain sends signals to change gonadal tissue and blood hormones.

How do you produce male and female fish?

These can be produced by manually sorting the fry for sex, by administering hormones to all the fry (male and female) during key growth periods, or by crossing different species.

What kind of fish live in groups?

Fish that change from female to male–including parrot fish, sea bass, and groupers–usually live in groups of one male and several females. Since the males guard their groups against other males, a small fish is more likely to reproduce if it’s female.
