I have 4 Oto catfish. Recently I saw that one of them was pregnant (about 3 days ago). I put all 4 in a separate 5 gallon tank away from my original aquarium (which had goldfish, who would eat their eggs). Today I went out and bought a plant for the catfish. How long will it be until they lay their eggs? When will I start seeing frys? What should I do when that happens? Im new at this, can someone help me out?
 
It sounds like you are doing things right. There is no way to tell exactly when they will lay eggs or hatch, but it shouldn' t be too long. There is a fairly large chance of course that this will not be a successful mating. Also as a side note, you should not have goldfish in a tropical tank for various reasons, their temp needs differ, food needs differ, they produce a lot of waste, etc. O' and BTW Welcome!!!

thanks, but the thing is, its a goldfish tank. when I went to the petshop, I asked the people there if they could tell me which catfish can live with goldfish. The guy there showed me plecos and otos. In the end he said he thinks otos are better because plecos can bother the goldfish sometimes. Thats why I have otos and goldfish.
 
Otocinclus breeding in an aquarium is a very rare thing. You may want to read up their spawning activities here:

Please let us know if she does lay eggs. Details!

Thanks

Help! I had only read that Oto's did not breed in captivity.
I was quite concerned, therefore, when I saw one of my Oto's looking "very" pregnant...or deathly ill.

I have a planted 60 gal tank, 2 fancy goldfish, 5 Otos and too many fancy guppies. The tank is around 24*C, 2 large driftwood, lots of plants including a huge lily with leaves averaging 6+ inches diameter. Water parameters very good. None of my fish have died or been ill for over 2 years. All five Otos were purchased approximately 14 months ago.

I have a grave concern that either my Oto's is horribly diseased with something...or pregnant. I don't know which so I am hoping if I describe her to you, you may be able to tell.

The other 4 Oto's have not altered in either appearance or behaviour. Lately one or two of these "healthy" Oto's are literally side by side or nose to nose with the Oto I am concerned for. While the Otos often roam/sit together (within a few inches to 1 foot) I've never really noticed this closeness to this degree. I am concerned they know something is wrong with her or, best case scenario, they are a mated pair.

Sick/pregnant Oto appearance:
Normal sized round/plump whitish tummy now hugely distended. Looks like a round small marble of approximately 3/8's of an inch in diameter. Tummy definitely round, neither oval nor flattish. Red streaks appear in the formally white area of her underside and tummy, including near face/jaw/mouth.

Sick/pregnant Oto behaviour change:
Once saw her hanging onto driftwood (vertically and right side up) with just her mouth and tummy about 1/8 inch from driftwood
Sits "on top of" a particularly flat sitting (underwater) lily leaf. The leaf is about 6-8 inches in diameter but she seems more interested in just sitting/sleeping there than eating on it. While she's there one other Oto seems always there as well.
While the Oto's go everywhere in the tank, the length of time she spends just sitting there is unusually long and the fact that the other Oto is there is very unusual.
The red streaks scare me and even her eyes look reddish and/or distended??

Sick/pregnant Oto behaviour non-change:
Still busily munches on algae and driftwood.

I would greatly appreciate your opinion.
 
unless you have simulated a wet and dry season in your tank there is almost no chance that they will spawn.

That is all normal behaviour please don't medicate your fish. Red streaks though is a little concerning check for ammoina if none is present don't worry about it.
