Neon goby and other Elacatinus Breeding/Spawning Overview

Postby aomont » Wed Dec 31, 2008 11:14 am



1 - Species covered in this forum:
Gobies of the Genus Elacatinus – This overview deals with gobies commonly known as Neon gobies or Cleaner gobies and related species. Some species in this group are:
– “Neon goby”
– “Sharknose goby”
– “Barber goby”
– “Yellowline goby”
- "Redhead goby"
– "Yellownose goby”
– Greenbanded goby”

For an overview of the whole Family Gobiidae, see

Here is a link specifically to known species in the genus

2 – Common characteristics:
These members of the Gobiidae family that come mainly from the Atlantic Ocean and, as their name say, many show symbiotic behavior and “clean” other fishes. In the ocean, cleaner gobies sit and wait for their “client fishes” in cleaning stations so they can remove and eat their ectoparasites. This behavior, coupled to their small size, makes them interesting fish to keep and watch even in small aquaria. They eat meaty items and are easy to feed, accepting from BBS and frozen food to flakes and small pellets.

For more basic information, visit http://www.wetwebmedia.com/neongobies.htm

3 – Reproduction:

3.1 – Sex determination:
Most Elacatinus are of separate sexes although E. multifasciatus, and probably E. puncticulatus, exhibits protogynous hermaphroditism.

3.2 – Sexual organization:
These gobies usually breed in pairs however, males of some species (as E. multifasciatus and E. puncticulatus) keep harems of several female and will spawn whenever one of them is ready.

3.3 – Sexing:
There are usually few clues to separate the sexes but the females tend to be plumper.
The best way is to observe a group as males display to one another and active females are approached from the side by the male forming a T (information on Witt´s book). Another way to separate male from female is looking at the genital papillae as the males have pointed ones while the females have theirs rounded.
As for the size, while in E. oceanops the female is longer than the male, in protogynous species (see below) males are larger and have a more robust head.
Male E. puncticulatus have fewer but more elongate dark blotches than females shows temporary color changes during courtship.

3.4 - Pairing / Setting Up Broodstock:
A formed pair usually hang together as they tend to form monogamous couples. If it is not possible to get a established pair, your best shot is to observe a group for behavior tips, as previously said. Pairing a large and a small adult fishes is also advised due to size dimorphism in some species.

3.5 – Courtship:
In E. oceanops, Male approach female from the side, making a T figure, trying to lead her to his den.
In E. puncticulatus, exhibit charcoal-grey color in the head fading to light gray or almost white near the tail.

3.6 – Spawning:
Gobies are demersal spawners and generally do so by the morning on the walls of a cave (it can be rockwork, underside of a shell or a length of PVC pipe). The male guards the cave, care for the eggs and fan them near spawning time.
For E. oceanops, spawns take place every 10 – 15 days, depending on temperature and time to hatch of the previous spawn while they happens at 7 days intervals in E. puncticulatus.

4 – Eggs:

4.1 – Size:
E. oceanops2 mm

4.2 – Quantity:
E. figaro – 140 – 700 (mean 410).
E. multifasciatus – up to 250.
E. oceanops – 50 - 250 (500 – 800 according to ORA website).
E. puncticulatus – 200 to 300.

4.3 – Characteristics:
Eggs are elongated and attached to the cave by one of their end and the larvae head points to the free end. The embryo eyes are silvery 1 or 2 nights before hatch.

4.4 – Incubation period/Hatching temp:
E. chiquita – 9 days
E. figaro – 5 – 9 (usually 6 - 7) days at 25C
E. multifasciatus – 5 to 6 days
E. oceanops – 6 – 8 days
E. puncticulatus – 6 days at 78-80F

5 – Larvae:

5.1 – Size at hatching: 2 - 3 mm
5.2 – Yolk sac present at hatch: almost none
5.3 – Mouth present at hatch: Yes
5.4 – Eyes developed at hatch: Yes

6 - Rearing:

6.1 - Breeding & Rearing Techniques:
Usual these species are reared with green water technique using either ISO, TET or NAN (either live or preserved) and are co-cultured with rotifers. Although some say SS rotifers are needed others state you only need L-type rotifers as long as you can keep their density (10 – 15/mL) so the larvae have an array of sizes to choose from.
Better results are seen using a BRT as a larvae rearing tank

6.2 – Day at first feeding:
Day 1

6.3 - Starvation Time:
Survival to 12 to 24 hours without food, depending on remaining yolk. (John Lauth - Personal information)

6.4 – Feeding scheme:
Larvae are fed rotifers since the beginning and these should still be offered until the larvae are feeding n NHBBS (day 17 to E. oceanops or 20 to E. multifasciatus and E. puncticulatus). NHBBS is offered from day 10 to 15 on. (feeding scheme summarized from Witt´s book).
AZaquaculture states they could raise E. oceanops until meta solely on rotifers but met time was delayed to 30 – 35 days instead of usual 18 – 25 days.

6.5 – Age at meta:
E. figaro – at around day 30.
E. multifasciatus – 29 to 35 days.
E. oceanops – starts at day 26 and may be delayed until day 45. (Witt)
E. oceanops – 18 to 25 days and may be delayed to day 30 – 35 if solely fed on rotifers. (AZaquaculture)
E. puncticulatus – 36 to 42 days.

7 – Species been reared successfully:
Many operations, either small and large, have raised species from this group so we will list the species we have record of being bred but will suppress the company/individual names so we don´t miss anyone.
E. chiquita
E. evelynae
E. figaro
E. horsti
E. multifasciatus
E. oceanops
E. puncticulatus

Hybrids produced:
E. horsti x E. louisae
E. oceanops x E. figaro

Marcelo
Thanks for this post. I am just hoping that it is not an April fools gift.
This is a great accomplishment for this community, thank you for sharing it with us.
