chc / Alex, in the first set of pictures I posted:
1. female
2. female
3. male - left side
4. male - right side
5. female - left side

Alex, when I do water changes, the new added water is cooler (but not cold) than the tank water. I do large (min 50%) water changes on all my tanks, including tanks with fry.

I think your fish are growing up nicely and already stunning! I think however that they are still a bit too young to spawn. Maybe in another 6 months they will be more interested in each other? But with cichlids, you never know because many will breed at much younger age/smaller size! From reading and research I've done, I think the riverine type you are keeping get much larger, 11+ inches! My largest lacustrine was at least 6 years old and was still only about 9 inches. I think because of this difference in size, the lacustrine is able to breed at smaller sizes.

I don't see any of the "rust" color on my lacustrine compared to the riverine type, however the olive green is more prominent with less spangling. It would be interesting to see if anyone could do more scientific research between these two fish because both types, in my opinion, seem different enough to almost be separate species (shape, coloration, size). Maybe that's a stretch and the differences can really be attributed to environmental conditions?


I got it right from your pictures (fish gender) good on me 8) It's numerous hours watching at my Rostratus paid off!
I also think that my fish is not mature yet, largest male just a lil over 6", others considerably smaller. They less than 2 year old.
Interesting observation: most flaring and tail beatings occurs after the tank lights is off. That’s only the time when I see them pay attention to each other, other then chasing. They do some body shaking, digging sand, but that’s about it for now.

Trying to add duckweed to Rostratus diet. At least once/twice a week. I have daphnia colony going at my backyard, and plenty duckweed small and larger on the top of the buckets.
Fish particularly like the very young plant, around 2-3 mm.
The picture looks like it's algae on the front glass, but it's floating duckweed in the body of water.

Keep us updated on how the duckweed feeding goes.

In my large tank it is clear that "someone" is eating the duckweed, but I haven't seen the culprit yet. I have rostratus and several other species in the tank. I assume it's the maculicauda doing the duckweed eating, but I haven't seen it with my own eyes yet.

Well, happy birthday Bas 8)
Have a long & healthy live, so you can enjoy you fish for a long while!
Chris, I start feeding duckweed from April of this year. None of the fish in my tanks are resisting. You should see Pearsei in 220 gal swallow pounds of it, he he.
As for Rostratus, they really enjoying this type of plant substance, but if I add leafs of Romain Lettuce they won't touched, seems Rostratus like smaller pieces, or it just taste different, I would not know, lol.
BTW, their (Rostratus) main diet from the time I got them is OSI spirulina flakes, they seems enjoying very much.
Sometimes I feed in the evening with some other food, like sinking algae pellets, very rarely dry krill , etc.
At least once a week, I skip feeding all together.
Seems working well for past 2 years or so..

Great info. Thanks!

I see you fast your fish from time to time. I do the same thing with my larger fish. It started years ago as an accident (just got too busy to feed a couple of times one week) and noticed the fish showed improved vitality. I'd say the manner in which I feed now is very unlike what it was years ago. I feed much more lightly, at higher frequency, than ever before with the addition of the fast day for the more predatory types in particular.

I have three varieties of duckweed right now (or at least one duckweed and two very similar varieties). Without exception, it's the "typical" duckweed variety that is eaten first. The larger variety is eaten next, and the type with the crinkled edges is eaten only when the others are completely gone. I'm tempted to do my own taste test! :)

Ha Ha, taste it man and let me know, what varieties of duckweed is the most delicious.
As for the predatory cichlids diet, I also add several snails 3-4 times a week. I have colony going in my 29 gal Pensil fish breeder. All you need is to throw several large sinking algae pellets and snails will concentrate on top of it, use small net and you get the meal 8). Fish does spit shell particulars out, but something must stay in the body. Cause fish skin and fins looks much better after I start it couple years ago.

I just got 4 of these guys @ 1" or so from Anubias Design (Mark Denaro). Are they as slow growing as A. altifrons?

Thanks,
Matt

Hi Matt,
Congrats on getting beautiful fish. Which one you have, riverine or lacustrine?
I didn't have chance to keep A. altifrons, but definitely seen much faster growing CA cichlids then A.Rostratus. I started this thread almost 2 years ago when I got these guys at 1". Today they range approximately between 5 and 6.5 " TL.

Rostratus don't bother adults, but do eat Otapa fry quickly.

I used to keep rostratus with Poecilia salvatoris and Xiphophorus alvarezi - a large, southern sworttail

As Poecilia fry go to the surface, they were not bothered by anyone (including the rather fiercely canibalistic swordtails) but swordtails, staying near the bottem were mostly eaten. Howrever, a few managed to survive, inreasing the population slowly
