Ancistrus sp. Wabenmuster from CSG convention spawned

Post by bekateen » Fri Dec 06, 2019 2:24 am

From the thread Re: 2019 Catfish Study Group Convention, the Ancistrus sp`wabenmuster` which I got at the CSG convention and brought back to the USA spawned about a week or two weeks ago. I didn't know it, but tonight I found fry with small yolk sacs loose in the tank. Thanks again to @jac for the fish stock. ^:)^ :-BD \:d/

Cheers, Eric

Wabenmuster babies. 1 week old, 10mm SL. I collected about 32 fry, although I lost two or three within days of their discovery.

About 16-18 days after this wabenmuster male first mated, he is now sitting on new eggs, laid between 9am and 3pm today. At about 50mm SL, he's my smallest male. His cave is an old bamboo cave with an internal diameter of only 12-15mm... It's very small. I have at least 2, maybe 3, larger males (about 70-80mm SL) hanging out in larger (25‐30mm diameter) caves but the big males aren't getting the action. I have at least 2 females and one very small unsexed fish; one female is bigger (~65-70 mm SL) than the other (~50mm SL). I suspect it's the smaller female whose able to fit in this small cave to spawn.

Cheers, Eric

I took the eggs from dad's cave so I could watch them develop. 34 eggs total, one is bad.

Sadly, that second clutch of eggs never developed. But happily, today I found another wabenmuster spawn, I suspect from the same small dad and mom (based on the size and location of the egg mass when found), although this one was resting loose in the tank on the gravel outside a dad'scave, lost or abandoned by its dad. I moved it to a fry net basket beside a powerhead to incubate.

Spawn sizes:
  • The first clutch, 32 fry.
  • The second, 34 eggs (none hatched).
  • The third, over 40 eggs, but I didn't get an exact count.


So there was about:
  • 16-18 days between the first and second spawn (as best I can estimate judging by how developed the first fry were when discovered) and
  • 25-26 days between the second spawn and the third. Hopefully this clutch develops.
In the meantime, I still don't understand why the large males and females aren't spawning but the smallest of each is.

Cheers, Eric

Thanks! :-) So far, this new egg mass still looks good. No bad eggs yet.

The third egg mass finished hatching yesterday. Two eggs turned white and never developed. One egg appears to have hatched early and died. The first three good eggs hatched on day 4: most of the eggs hatched on day 5; the last four good eggs hatched on day 6. Yesterday eve (day 6) I counted the live wigglers and found 48. Wonderful.

Cheers, Eric
