hey guys, i currently keep BN plecs in all my tanks to keep the algae down, but today *** read they can suck up unguarded fry or eggs!
could this be the reason i havent seen a single fry?

*** bought my j.marlieri then they were like 1.5 - 2inches, and had them for like almost a year.
+brevis pair for prob over 6months...
(so they are of breeding size and age)

what else could u use to keep the algae down that wont try and eat my fry???
*** been dying to see my 1st tangs spawn

apon ispection i have noticed the bristlenose plecs arent really noticed 100% of the time!
it seems the julies and brevis sometimes dont see thm sneak in
is it possible they are snacking on eggs or fry?

my multies are the only ones wwith a good colonial defense to ward them off,
i just saww a baby multi nip a full grown bristlenose! :lol:

maybe give them a treat? big water change?
a trigger would help start the process.

And that right there just convinced me that I need a bristlenose pleco in my 29gallon multi tank .

This is going to sound like sacrilege, but as long as your nitrates don't get completely out of control, you might also try skipping a water change before doing the big one. Granted they're not tangs, but I had some royal blue peacock cichlids and every time I went out of town for a few weeks I came home to find the female holding eggs .

It seems some BNs snack on eggs while other guys have no problems with them.
If your fish are already breeding, I think you already know why you see no fry.
No catfish I know of is cichlid egg safe.
Sure folk raise cichlids in tanks with BNs but that does not mean they won't eat eggs at night given half a chance. 6 months is a long time for adult brevis to go without spawning. Your Julies are still very small for their species and prob not breeding yet. But that will not stop them from raiding brevis eggs and fry given half a chance.

thanks for the comments guys.

yeah *** tried extra water changes, *** tried skipping water changes... nothing happened.
*** tried using rift lake salts with seachem tang ph buffer, and even tried no salt or buffers (in hope of more stable water perameters)
and nothing :x

each of these i tried over a long term basis, i didnt ry it all in a short period of time thatd be nuts :lol:

even tried numerous foods, but no success...

my julies are like 2.5 - 3.5 inches and exhibit all the breeding behavior *** read about + youtube footage *** seen of spawning julies.
*** just never seen any fry :fish: :fish: :fish:

should i remove my 3 bristlenoses just to give them a better chance of breeding successfully?
or maybe my 2inch calvus?

any suggestions would be great

"90gal - tangs: 8 j.marlieri, 20+ multies, lone calvus +breeding BN plecs."

If the parents are guarding the eggs, the pleco should stay away. But looking at your signature, I think you might have too many J.marlieri in there. I don't think your tank, IMO, can support more than 2 pair; most likely 1 pair. And those are marlieri, they are bigger julie. They might just be immature.

yeah i bought 8 and i am waitin to see the 1st pair emerge and harass the rest, so then i can remove the remaining julies...
but all i have seen is the big momma has claimed the caves and 1 lil julie is allowed in (presumed male).

the lil ones fight/challenge each other and change colours, and the big ones fight each other too...
duz this mean the males and females fight amoungst their own gender to establish some sort of heirachy?

duz this mean theyre still maturing and beginning the pairing process?
*** heard julies are pretty nasty and will ward off the remainders, but i havent seen that yet, is it easy to notice?
