Well scanning over aquabid I located these and have a feeling these should go well with the Paratilapia Polleni in the 100. I have to admit that when I see rare or threatend or listed endangered species, it gets my attention. While these are F2's I think it worth while to try these out. Low price too, and I suspect not very common in the hobby. www.aquabid.com/cgi-bin/auction/closed.cgi?view_closed_item&fwcichlidsw1221271206If page is not viewable these are Tilapia (Coptodon) bythobates - F2 Amazing, Rare, 2008 IUCN Red List of Threatened Species |

As always pics when you can!!! Are they in the same tank as your Polleni?

Thank you also Carl because I've actually changed up my acclimation methods due to your information. It used to be I'd just temp in bag them, and then add a few cups over time span to the bag. Since you brought out about the ammonia build up in a bag of shipping going 2 days or more and better the drip or their own bag water acclimation, it seems to prove more effective.

One of the new bythobates appears to have a misformed jaw area. The only good thing I can say is that at least having six of them, odds of getting at least one good spawning pair should be high. Also the Polleni, a few of them do appear to darken in the fins and body, showing a very deep black, but what I do find strange is that it seems to come and go, it's not an overall constant. There are two of them though the fins, dorsal, pelvic, and anal fins are getting close to Jet black and stay. They will morph slightly in the body, darkening, but about a hour or so later, that black seems to fade back. Really unusual. Bill if you know anything about that, I'd love to hear what you think.

body malformation is almost always a sign of imbreeding. the most common one i see are anal and pec fins joining at the back with no real tail or having a bent spine. what do you do to ensure no inbreeding?

I would guess that you pair up certain pairs that have spawned before? With the Africans of course, you never put fry back in the adult tank where the parents might be? Inbreeding as I understood it would take many generations of that to occur before you'd have issues like that. I could always try to locate a completely different seller of this species and basically try to mix the two different bloodlines I suppose.
The one I was really hoping to hear your thoughts on were the Polleni being dark then seeing it kind of fade back to grey, but of course if you have thoughts on inbreeding, that's always helpful too Bill. You are the Tilapia man ;D

lol. where these fish came from were probably the same breeder. many don`t take the pride you do in "clean stock". i can guarentee if these are all related through inbreeding, he wouldnt have taken the malformed ones to market. insted they would have been destroyed for no fault of their own. but because the parents look clean doesnt mean much in this day and age of fishie farms.
on a similar note...the selective breeding program i`ll be doing at my farm is designed to avoid these problems as well as creat a "prettier fish" that will sell at market better. we will be tagging all parents and we are starting with 15 or more different gene pools. i have found 7 so far.

Thats a point well taken Bill and I'll do whatever I can to keep inbreeding to a minimum. In the case of my Flavus species though, there isn't much choice short of buying a new group since I lost my female. Some of any new females in the surviving fry I have, that grow to adulthood would end up being bred again with their father unfortunatly. If I don't keep females in there the male in the main tank is going to go nuts.
Now with those Yellows, all I have to do is keep the males away from the female, which would be their mom. Any females I could breed back with my males, since their father is the male I have in my 75 gallon, not here.
What do you think about those Polleni? The fading in and out of black? Never seen a species really do that before. These are supposed to be the small spots, the ones less common in trade.

talking to ya 2 places at the same time! am proud for what you're doing - in the true wild, fish breed and survive or decline from survival of the species - I believe what you're doing is GREAT - you're not creating a hybrid but a healthy strain o fish - congrats at finding 7 pairs in that short of a time out of thousands of fish! good job Bill, I told you something really good would come of this!

sorry Jon, didn't mean to distract from your thread - the 2nd part of Bill's reply is what I was referring to....poor timing on a good post

It's a very mixed tank. 80% is all juvenile Mbuna and Haps. They are all about the same size, actually though the Tilapia are probably, both species of them, bigger then the Mbuna, but smaller then the Haps. There are a pair of snakeskin Gourami, 1 male adult Flavus, and a pretty good sized Hop Lo. The rest are an assortment of Cories, and a couple clown plecos. I never see any fighting going on in that tank. That tank is a pretty active tank though. I weeded out about 30 or so mixed hybridized peacocks this week, and should have the rest of the hybrids out next week.

I have to say I suspect it started showing now Bill. I had to move or begin to move the group of Albino TR haps up to the 100. Had a power outage that shut down the filters in the 15 gallon and the AC 50 never started back up, lost all the bacteria, and fish started hanging out at the top. I moved about half (25) of them up there. Found about 5 of them dead and being eaten up.
One of two things. Either it was a shock moving tank to tank, maybe the PH is a little higher in the 100 since the 15 had a crash on the filter and isn't always stocked, or it's those Tilapia doing just like you said. I still have another 25 in the 15 yet to move up. They aren't small small, but aren't exactly large yet either. Hard to say at this point, but I never realized that young female brooded up 50!!
