Gona Re Zhou | | Water conditions: Neutral | Water temperature: 24-27oC | | Disposition: Somewhat aggresive on occasions | Community tank?: Never | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems:
Poor fry survival rate | | Sex ratio: Somewhat male heavy | Breeding difficulty: Average | | Sucess: Fairly sucessful | Years Experience: 5 | | Other Comments: these fish must be well fed, or the larger fry eat the smaller very quickly. Best to separate larger individuals and don't keep them in too bright conditions | | Date this record created: 3rd October 2007 | Breeding date: 3rd October 2005 | | Breeder: | Location: |

Gona Re Zhou | | Water conditions: Neutral | Water temperature: 24-27oC | | Disposition: Somewhat aggresive on occasions | Community tank?: Doubtful, only with VERY calm fish | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems: none | | Sex ratio: Roughly equal | Breeding difficulty: Difficult | | Sucess: Fairly sucessful | Years Experience: 7 | | Other Comments: I raised 20-25 in a group - separating the top male as soon as he looked big enough to eat the smallest siblings. I also removed the 4 smallest fish and raised them separately.
I then bred them as 4 trios (in 18x10x10s) and a large group of 6-8 males with 2 females (in a 24"x18"x15").
Fairly peaceful - the largest males in the large group continually displayed, sparred and mouth wrestled nothing life threatening - although most had damaged mouths after a while. One or two smaller males subdued their colours, and to all purposes acted as females - avoiding confrontation with the larger males.
The sparring could be reduced by lowering light levels on the tank.
All four males kept in the trios (and therefore away from other males) had undamaged mouths. | | Date this record created: 3rd September 2007 | Breeding date: 1st May 2007 | | Breeder: jules | Location: UK |

Gona Re Zhou | | Water conditions: | Water temperature: 24-27oC | | Disposition: Somewhat aggresive on occasions | Community tank?: Only with species of similar size | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems:
Poor fry survival rate | | Sex ratio: Roughly equal | Breeding difficulty: Very difficult | | Sucess: Fairly unsucessful | Years Experience: 5 | | Other Comments: Habitats in Moz differ from that in Zim. Fish addapt easy to any tank, but grow fast (eating each other). Usually found with Orthonotus and/or Rachovi. | | Date this record created: 25th May 2007 | Breeding date: 25th March 2006 | | Breeder: Johan Jordaan | Location: South Africa |

Gona Re Zhou | | Water conditions: Neutral | Water temperature: 24-27oC | | Disposition: Very aggressive | Community tank?: Never | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems: none | | Sex ratio: Roughly equal | Breeding difficulty: Difficult | | Sucess: Fairly sucessful | Years Experience: 7 | | Other Comments: I had a good hatch of furzeri earlier an the year. As usual a couple males quickly outgrew the rest, and when I saw a 2cm fish swimming along with a 1cm fishes tail hanging out, I knew I was too slow to split them. However split them I did - I found that all the really small fish (the ones that would have been eaten) grew to be mostly females. The slowest growing fish (as usual) lived by far the longest - and in fact I still have 1 male and 6 females.
All the quick growing alpha males died months back.
Being top dog really does seem to shorten the lifespan of nothos!

Poor egg survival | | Sex ratio: Somewhat male heavy | Breeding difficulty: Difficult | | Sucess: Fairly sucessful | Years Experience: 6 | | Other Comments: For the first time I decided to keep a batch together rather than split up the pairs. I have about 7 males and 4 females in a 18 * 22 * 12 tank - lightly planted. The largest male quickly outgrew the others and then snuffed it. Theres always one. The others are doing fine - they are boisterous but the tank is square (ish) with no obvious terrotories, and so they seem to get on fine. They are ALWAYS hungry though - well and truly outeating all my other killies | | Date this record created: 17th February 2006 | Breeding date: 31st December 2005 | | Breeder: jules | Location: uk |

Poor egg survival | | Sex ratio: Roughly equal | Breeding difficulty: | | Sucess: Fairly sucessful | Years Experience: 5 | | Other Comments: The biggest problem with this species (for me) in the variability of development in eggs. Traditional wisdom says a long inc time, but many people have found that some eggs develop in weeks rather than months. I recently searched througfh a 1 month old bag of eggs. Found a few eyed up. Didn't have time to hatch them, so waited 10 days. When I came to wet them, none hatched - all dead. The eggs develop at almost any time between 1 and 6 months, and often don't survive long. To suceed with these, you must wet peat regularly, or at least find the eyed eggs and hatch asap | | Date this record created: 3rd December 2005 | Breeding date: 3rd December 1990 | | Breeder: jules | Location: UK |

Gona Re Zhou | | Water conditions: Neutral | Water temperature: 24-27oC | | Disposition: Somewhat aggresive on occasions | Community tank?: Never | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems:
Poor fry survival rate | | Sex ratio: Roughly equal | Breeding difficulty: Very difficult | | Sucess: Fairly sucessful | Years Experience: 3 | | Other Comments: The species is extremely short-lived (three months on average) and the fry exceptionally fast growing. It is very easy to stunt their growth and then the result is low productivity, but if properly fed and with good water quality (daily changes) they are quite productive. The breeding window is also very short just a few weeks.
The fish live longer if kept at lower temperatures (22?C).
The incubation time is very erratic and if the eggs are incubated too long the fry are weak and many die. The eggs should be checked regularly (every month).
In general, it is a challenging fish. If all things are done properly they grow nicely and are productive spawners, but it is unforgiving of any mistake. | | Date this record created: 13th March 2005 | Breeding date: 10th March 1990 | | Breeder: | Location: |

MOZ 99-4 | | Water conditions: Moderately hard and alkaline | Water temperature: 24-27oC | | Disposition: Very aggressive | Community tank?: Doubtful, only with VERY calm fish | | Spawning Method: Peat (or similar) spawning substrate | Breeding problems: none | | Sex ratio: Roughly equal | Breeding difficulty: Very difficult | | Sucess: Average | Years Experience: 1 | | Other Comments: I found these fish to be aggressive; a tank of fish can be quickly reduced to shreds by one individual. The much smaller females (because they are continually outcompeted for food?) are harassed all day long.
The fry are large and quick growing. I've found most eyed up eggs after 6-7 months
