Clutch - The deposit of eggs left by a female fish. See Spawn.
Community Tank - An aquarium which is populated with fish of several different species, all of which are compatible with one another.
Clutches(Eggs): Pale pink to reddish eggs are deposited above the waterline and are closely attached to each other. Their size varies from 2.20 to 3.5 mm (0.5 to 0.9 inch) diameter. An average egg-clutch contains 200 to 600 eggs.

In July 2002 I received a wild caught pair of this stunning new, larvaphile mouthbreeding and scientifically undescribed Apistogramma species. It was a surprise gift from a fellow Apistogramma mailing list member.
Eggs that die are consumed by the parent(s) to prevent fungus from developing and spreading to the rest of the living clutch. a) "Field Observations on the Reproductive Ecology of Three Species of Armored Catfishes in Paraguay.
Do not be surprised if they eat their first clutch or two. They are easy to breed, but are best kept in their own breeding tank with another fish that takes the "punishment" of aggression from the parents.
One of them, a huge Acanthicus adonis sized about 30 cm was obviously too large and powerful to be stopped by the cichlids so, after losing 4 clutches of eggs we decided to remove both A. adonis specimens from the tank.
Furthermore, if one has successfully raised a decent clutch, say over 20 fry, and brought them to the point of resembling miniature versions of the adults, then be prepared for some truly frantic activity.
Some pairs will produce a new clutch of eggs every 4-6 weeks. Clutches can range from 40-250 fry.
[edit] Special Notes
The Ancistrus species like many plecos has an interesting adaptation of being able to live in water with reduced oxygen.
The male sticks with the clutch, and prefers to sit in the area of strongest current. Although he is capable of burying himself along with his clutch, he usually chooses not to.
The female lays a clutch of 150-200 eggs onto a flat surface and guards them until hatched. There have been reports of fry being guarded as well. Both males and females of this species exhibit dioecism.
Green puffers are notorious fin-nippers.
10 on the upper surface of the cave and produce a clutch that ranges in size from 40-100. [2][7] Both parents provide active brood care, typically lasting 21-28 days [2], which includes guarding, herding and feeding.
A female Pomacea snail will lay her eggs in clutches above the waterline, generally at night. Usually 200 to 600 eggs can be laid. Eggs of Marisa snails are also laid in clutches, but below the waterline, on vegetation.
Breeding Information: Cave spawners, the already reclusive julies may seem to disappear altogether when guarding a clutch of eggs.
As with other Julidochromis, this species may spawn regularly producing small numbers of eggs, or less often producing larger clutches. Fry will be tolerated by the parents initially, but may be chased away once they reach an inch or so in length.
Many snail species are hermaphrodite, apple snails are not, and need both male and female to reproduce, they lay their eggs in clutches an inch above the waters surface, if you don't wish to breed them simply remove the eggs.
Some time on Thursday, we discovered a clutch of "small fry," that is, a second spawning. These fish were clearly smaller than the first bunch.

Typically, a clutch of 6 or 10 eggs is released into the brood chamber.
The photo above on the right shows a pair (upper fish male, lower female) over a clutch of eggs. The Bolivian ram is a substrate spawner, laying the eggs in a depression in the substrate or on a flat rock or piece of wood cleaned by the female.
0, usually yields fry in a relatively even ratio of males/females. The ideal water temperature is around 80 degrees. Lower or higher temps can affect the size of the clutch and even the sex ratio of the fry.
I have tried several couples, have a couple in a breeding tank right now, but I have never even had a clutch of eggs. I know from other breeders that they are kind of hard to get going, but if they do they never stop.
The female Severum will deposit the eggs on a horizontal surface, usually a slate or round rock (if one isn't present, one should be added to keep them from laying clutches on larger, harder to remove items).
During spawning, a male will guide a female to a spawning site where he will undulate his body next to hers, causing her to release her clutch of eggs which he will fertilize externally.
A good brood has 250-300 eggs, although clutches up to 400 have been reported. Both parents guard the eggs, which hatch in 2-3 days. The fry are very small and difficult to care for.
The female remains close the spawn and is primarily responsible for maintaining the hygiene of her clutch. This involves fanning the eggs with the pectoral fins and removing infertile eggs (which turn white) by eating them.
