This is my first post on PlanetCatfish, I have lurked for awhile but not really had anything interisting to contribute. I recieved a group of Rineloricaria sp. three months ago and put them in with a group of wild angels and blue tetras. The fish are housed in a 150 gallon extra tall. I noticed pairing behavoir two weeks ago and left the tank alone for a day or so and was rewarded with a clutch of eggs laid on the front pane of glass. This was on the 27th. The male sat guard on the clutch until the 29th. When he abandoned them I removed the entire spawn with a new razor and a siphon. I was unsure if the eggs were abandoned because of pressure, fear, or unfertility. I decided to take a look at an egg. There were 49 eggs in all, three fell to the gravel and I was unable to retrieve them.

Photos: I hope you enjoy








I have a video but it is loading slowly. It clearly shows blood flow from gills to abdomen. I am working on getting it up.
Anyone know what these fry are going to want to eat? Its my first Rineloricaria spawn so I am in the dark, Were it an Angel, Discus, Tetra, Cory, or Apistogramma I know what to do next.

Well done with the spawn & the stunning photos

nicely done

Personally I happen to have a group of Rhineloricaria (like) fish which reproduce regularly, but providing white eggs

Does anyone know whether the colour of the eggs is anyway relevant??

I make up a thin 'jello' out of spirulina powder and agar. I also disolve spirulina powder into a paste and smear it on surfaces the fry can graze on, have had success with smearing it on cylinder shaped filter sponge placed in the tank.

Thank you, I will try this method. I was thining about waiting until the yoke sac was gone.

First of all i want to congratulate Chris's successful spawning of what looks like a very interesting species. i haven't seen a live one of these yet.
I would recommend that the fry be kept in a net breeder for their first couple weeks then in shallow water for the first 2-3 months always with strong circulation and aeration for good luck. This group of catfish fry usually begin to eat on about the 2nd day or so after the yolk sack is hard to see or apparently absorbed. These fry are challenging to raise.

Hi Bas,
The newly laid eggs of your catfish should look exactly like those in Chris's excellent photos and should only get darker with every passing day. Most hatch in 7-8 days after been laid if the temp is near 28*C. They begin to earnestly feed a couple days later. Translucent white is OK as long as after the first 24 hours the eggs begin to darken from embryological development. They can sometimes spawn without a male present and in such a case the eggs will quickly decay or be eaten by the female or other fish since females don't play an important role in brood care.
You could siphon the eggs as you slip them off the glass with a single edged razor blade. Siphon them into a net breeder set in a bucket filled with ~3 cm of the spawning tank water. Then hang the net breeder in the spawning tank near a filter outlet.

Hi Larry

Thanks for your effort, but I've raised almost 100 of the fry by now - so I think I managed this task

In my case, the fishes come from Uruguay, I keep them colder (today 12 C, been at 10, but in summer naer 25) and they will spawn again in April or May. This winter I actually devided the group, as I had always only 1 dominant male breeding - now I created 2 groupes, both with a spawning place as similar as possible to the former one. The groupes are 2/3 and 1/3, thus both 4 fishes

Ny question, however, referred only to any taxonomical relevance

Hi Bas,
I guess I misunderstood your question about the eggs' color. i inferred that you were wondering if they were viable. Sounds like you know more about the species you have than most.

I am not aware of any species of that do NOT produce green eggs....

But doesn't infertile eggs turn white with time (like Cory eggs for example)? I'm fairly sure that my Sturisoma eggs turned white when the male hadn't done "a proper job" some time ago.

It sounds like Bas is saying his eggs are white and hatch out for him.

Nah, I think Bas is saying his fishes eggs are fertile, but not green. Inferring they may not be .

Sturisomatichthys?

@ all,

The eggs start white, are some 3 or 4 mm in diameter, and after 2 or 3 weeks the hatch. The first week they remain white, than they thurn darker

The fishes come from a river in the region Rivera, in Uruguay (I did not catch them myself, they were sent to me, so I know nothing more)

I wrote earlier something about these here: http://www.planetcatfish.com/forum/view ... =5&t=21294

Perhaps any discussions about my fishes would better be held here? I did hyjack this topic, I'm afraid

It took about five days from the completion of the eggs being laid to the last one hatching. They stayed green the entire time.

Chris - -- cheering for your little fellows. Photo when possible!!
Please

The fry are growing and swimming. I am not sure how fast they are supposed to grow?

Congratulations with the fry
I have breed the Rineloricaria sp red, and my experience is that you shall have just 5-8 cm. water in the aquarium in the first few weeks. In a full aquarium couldn't my L010a fry find food (they died of starvation), and it was therefore I am raising them, with just a little water in the first 3 weeks.
- I hope you understand my bad english..

Chris - Terrific pics.
