Panda Barbs Spawning

My panda barbs are some of my favorite fish.  Very active, very pretty, very prolific and always willing to put on a show.  Here they are engaging in their daily spawning routine.  This happens about an hour after the lights come on, and continues until I feed them.  I am sure that if I removed the fish from this aquarium I would have thousands of fry appear in a few days.  When I want to collect eggs, all I have to do is move the male and one female to a 2.5-gallon tank with a yarn mop and they will happily fill it with hundreds of eggs.  Enjoy…

Nannacara aureocephalus ‘Sounourou’

Not all of the cichlids I keep are from West Africa.  Here is a group of cool dwarf cichlids from French Guiana, Nannacara aureocephalus ‘Sounourou’.  I got them as small juveniles in November, 2011, from Cris Moscarell.  I have found the species to be very slow growing, and they are just now starting to show some spawning behavior.  The females wear a very chromatic black and yellow pattern, so you will be able to pick out the spawning female from the group.

The tank is a 25 gallon (36″x13″x13″) filtered with a Poret foam matten filter (air driven).  The tetras you see in the video are Hyphessobrycon peruvianus.  I am using about 1/2 RO in this tank to soften the water, but I am not adjusting pH.  If the pair does nto spawn soon, I will switch to straight RO for a while.  If that does not work I will start to drop the pH a bit.  Hopefully I will be able to shoot another video of this species in a few weeks… when they are raising fry!

Repashy Spawn and Grow

Ever thought about the differences between fry and adult fish?  There are a lot of differences, especially with regards to what they need nutritionally in order to grow quickly and with good health.  Repashy Superfoods’ new Spawn & Grow formula is designed with fry in mind.  Here is a video I put together talking about raising fry in general, and how Spawn & Grow can help…

Corydoras caudimaculatus… Afternoon Delight!

I have been working on conditioning this group of catfish for a few months.  When I got them they were thin, but not a single fish died.  I have always liked this species, but never had any success breeding them.  But neither have I ever had this many at one time.  I noticed breeding behavior for the first time a couple weeks ago, but the catfish shared the tank with some rainbow fish grow outs and a LOT of horn wort.  I got all that cleaned out over the weekend, did a big water change and added the yarn mops you will see in the video.  I noticed that the fish were spawning when I went into the fish room at about 5:00 this afternoon.

Parananochromis gabonicus Defending Their Fry

Next month marks a year since the trip to Gabon to collect fish.  Here is a video of one of the cichlid species I brought back, Parananochromis gabonicus.  I had been keeping pairs in 20 gallon aquariums up until about two months ago.  The pairs were spawning, but in between spawns the males were very rough on the females.  Plus, the males were going to outgrow the tanks.  I moved all of the fish (two males and three females) into this 40-gallon breeder aquarium, added a big pile of wood for cover, a school of hardy tetras (Moenkhausia agnesae) and four or five well hidden breeding caves.  A few weeks ago the most dominant male and one of the females spawned, and chose the most observable cave to breed in.  Good fish!!!

When the pairs were spawning in the smaller tanks there were no target or dither fish in with them.  The female would turn her defensive attention on the only other fish in the tank… the male.  This led me to believe that the male of this species does not take an active role in caring for the fry… not true!  As this video documents….

Parananochromis gabonicus

This video shows a young female Parananochromis gabonicus caring for newly free swimming fry.  I brought the pair back from the Gabon trip in February, and they lived with a group of eight in this 20-gallon long aquarium.  By late March there were a few fish becoming mature enough to defend territories, so I removed all but two males and two females.  I did not see much indication of spawning until I was able to drop the pH to under 5.0.  I had already placed four caves in the tank, but the fish did not show much interest.

When we were in Gabon, Anton Lamboj and I were discussing the micro-habitat where these fish were found, and he suggested that Parananochromis species may be ‘leaf divers’, meaning that they like to bury themselves in leaf litter (which explains why they are not easy to net).  Other leaf diving fish I have kept (some Betta species, catfish and some South American cichlids) also chose spawning sites in dense plant matter, so I decided to fill all of the spawning caves in this tank with long fiber sphagnum moss.  That did the trick.  Within a day the females were exploring the caves and their abdomens turned bright red.

The spawning occurred in late May, and was evidenced by the female becoming very reclusive in the cave and also very aggressive to any other fish that came near the opening.  The fry did not appear until 12 days after the day I think they spawned, and this video was shot on their first foray (that I noticed) away from the spawning cave.  One of the interesting observations in the video is that the female takes many of the fry in her mouth, and keeps them there, when she feels they are threatened.  Other west African cichlids I have seen do this (other than the mouth brooding species) usually just relocate the fry and spit them out.

This is the first cichlid that I brought back from Gabon that has bred for me.  Hopefully the strategies successful with P. gabonicus will also prove effective with the others.

Melanotaenia praecox

Here is a short video of some rainbow fish spawning, which they do every morning within a few hours of the light coming on.  I am not trying to save any eggs, so I have not put a mop in the tank, and the bows are laying eggs in the roots of the Anubias nana growing under the driftwood.  The German blue rams sneak in and steal the eggs, but new eggs are very sticky and the rams do not like them.  After a few hours the eggs lose their sticky coating and the rams will eat them all.

Hemichromis frempongi

My H. frempongi pair are breeding again.  This is their second spawn.  The first time around it was interesting to see how long they doggedly protected their fry.  All of the other jewel cichlids I have kept tended to lose interest after 4-6 weeks, eat whatever fry were still around and then spawn again.  This pair were still caring for their offspring twelve weeks after spawning, and the fry were starting to lose their juvenile color pattern.  At the end there were only 10 juveniles left (because I had been removing them steadily over a couple months), but the parents would still come charging out to defend them when anyone would appear in front of their tank.

H. frempongi is a very aggressive 5-spot jewel cichlid that is endemic to Lake Bosumtwe in Ghana.  Of the three 5-spot species (the other two are H. fasciatus and H. elongatus), this one is medium in size (the largest male I have ever seen was about 9″), the most ‘cleanly’ colorful and (in my opinion) the meanest.  Establishing a pair requires a lot of fry to grow out and more than a little luck.  I started with 24 one-inch fish, and six months later I was fortunate to have two left that were male and female… and not trying to kill each other.  It still took another 4 months before they spawned for the first time.

When the pair does not have fry they are shy and hide a lot.  When they have babies they are the polar opposite, as this video will show you.  These have become my favorite cichlids in my fish room.  They are entertaining, to say the least.  Enjoy.

Xystichromis sp. ‘Dayglow’ & Melanotaenia sexlineata

Most of my aquariums are not perfect examples of biotope communities.  Too many species and not enough tanks.  This aquarium was set up to be the home of a colony of Xystichromis sp. ‘Dayglow’, one of the Lake Victoria basin species I want to maintain.  I have one male and four females that I have grown up from 1/2″ fry.  I started them in a 15-gallon tank until they were showing adult colors, then moved them to this 40-breeder.  They have turned out to be very shy fish, and when they were in this tank alone I almost never saw them.

I like to use rainbow fish as dithers in peaceful to moderately aggressive cichlid tanks, especially when the water is harder and higher in pH.  Since these Victorians are not too large or mean I chose to move my colony of Melanotaenia sexlineata ‘Tabibul’ in with them.  This is a beautiful medium-size rainbow that is becoming more common.  The work perfectly as dithers adn now the cichlids stay out front all the time.  Hopefully they will spawn soon so I can grow this colony (five fish is too few!).
