View Full Version : My first colony

12-12-2008, 12:57 AM
Hello, Trophs.com:

I acquired my first colony of Petrochromis on 2008-12-09. I got 20 Petrochromis Famula "Nyanza Lac". I had the choice of 15 Petrochromis Trewavasae (unknown collection point) or these Famula. I traded in 34 F2 Tropheus Duboisi Karilani, 9 F1 Tropheus Moorii Nkonde Red Sunspot, and a modest sum of cash to acquire these guys. I wanted to clear out those Tropheus and try something different anyway, so there we go. Petrochromis are especially uncommon in this area, so I decided to jump on this while I had the chance!

These Petrochromis were owned by another local fish keeper, who traded them to the LFS, who then sold them to me. I believe they're F1. They are about 4" average size, with some a bit smaller. If I was to go on "colours", I believe I have about a 1:1.5 (8:12) ratio of Male:Female; I have not vented them.

They're still settling in, and I just added two large Texas Holey Rocks (one at each end of aquarium) yesterday (day three). They're eating NLS 1 mm Cichlid Formula with vigour, but I think I may need to get the 3 mm instead, as these pellets seem a bit small for them.

I have them under 4 48" PowerGlo T8 tubes, but I may switch out 2 of those for LifeGlo II tubes. The dominant male is colouring up quite nicely. The previous owner says they were showing signs of breeding for him before he parted ways with them, so I hope they will continue that behaviour once they settle in.

I have treated prophylactic using Metronidazole to prevent any possibility for "bloat" to occur (fish moved from original keeper to LFS, then from LFS to me, all in the space of 4 days). So far, so good. I haven't taken pictures as of yet, but I will add to this thread when I do. Petrochromis keepers are few and far between in my area, so I need to use the resources of this forum as much as I can.

I believe "sully1000" is keeping these so I will pay special attention to his posts and see what I can learn about this variant. Thank you for reading, and I look forward to any advice as to caring for this colony. I believe they are the only colony of their species (collection point) in Manitoba; they were originally imported by the aforementioned LFS in Summer 2007.

Hope you went through the whole treatment or you're just causing more headache.

Pay special attention to them for a week or so and watch their behavior for aggression issues.

I agree with feeding them a 3mm pellet as Petros are voracious eaters. Watch the water quality though as feeding them good and trying to get them to breed will spike the water to a poor quality very fast.

Good luck and have fun with them, Petro's are great.

I am looking forward to seeing your pictures. I would also like to hear your opinions on them versus keeping trophs.

I have my first confirmed holding female, just under four weeks after acquisition.

pug: My opinion ... not as colourful as Tropheus, not even close. Contrary to everything I have read, these guys are not "Tropheus on drugs"; in fact, I find they are less active than Tropheus colonies I've kept. Aggression has been minimal, and zero losses after four weeks. I wanted something different for a while, so I'm going to stick with these guys, but I don't know if I would "bother" with getting another colony of Petrochromis.

I will update this thread once I see how this whole breeding thing goes. :)

Dang how small is their tank?

eklikewhoa: 48" 24" footprint, about 18" inches deep or so.

I have about 30+ juveniles from the "Nyanza Lac" colony growing out in a separate aquarium, and two or three females are holding again. I made the mistake of stripping too early on several occasions so I am going to let these girls go at least two more weeks before I strip 'em. 15+ of these juveniles are in the 1"+ size and are now about 60 days of age. I think I will bring the required five for BAP (Breeders Award Program) at an upcoming local aquarium society club meeting / auction.

I have lost 4 of the 20 adults ... one was a jumper from when I had no lids on the aquarium, and three others from skirmishes within the colony. The dried jumper was too tough to identify the gender, but the other three appeared to be males.

I went through this with a group of Tropheus Duboisi a couple of years back where the colony thinned its numbers by killing off "excess" males one-by-one. That being said, the resulting tropheus colony was very prolific. I think sometimes, after you move a group of fish, you need to allow the group to re-adjust its dynamic, which sometimes means adjusting their hierarchy? :|

The aquascaping has been modified heavily, and all of the flowerpots are removed, although the rockwork is still quite sparse. I need to work to fix that situation. Well, that's enough of an update for now. I won't post any more pictures until I can do something about the rockwork situation.
