As I mentioned in another thread, I want to try to breed my dwarf pike cichlids, but I am pretty sure I will need to have real blackwater conditions, as they have not showed any signs of breeding so far. But my water is already very soft. I hadn't measure the parameters for a long time but...
I have a pair, well a male and a female anyway, in my large cichlid tank, they are I think Wallaciia cf nothopthalmus sp Orinoco. I have had them well over a year now, I did have another female but unfortunately she died not long ago. I was speaking to someone else who also bought some at the...
Just reading through this thread, which I missed before. As I understood it these fish are not being farmed as such, just collected, moved and stocked in a more convenient location close to Iquitos where they will be easier and less expensive to capture. So they are being caught in the wild...
Here is some light reading for you - according to this recent paper, if I understand it correctly (I still have to read it thoroughly) M. insignis and M egregius cannot be distinguished as separate species using molecular analysis, and there are probably more undescribed species.
Couldn't...
I thought the other ones you had were mirificus not festivus?
I am not sure how accurate the drawings are, but it does not look like egregius, not only because of the two bars in front of the spilt bar, but also the diagram shows 5 bars after the split bar and before the tail, yours just has 4...
For a long time I had beckfords pencilfish together with neon tetras, I really liked the combination. I honestly think the beckfords are just as attractive as mortenthaleri and the other more exotic pencils, even though not as brightly coloured, they are hardy and interesting to watch. They...
Exactly, as the water level goes down the plants occupy more and more of the space, some will flop over, it will be really hard to see where the fish is hiding and very hard to move a net around. The trap method works well with very little disturbance to fish or plants. The only downside is...
I have had success with traps made of plastic drink bottles. Simply cut the top off and invert it inside the bottle to make a funnel. Make a hole in the bottle so that it sinks easily. Put some food (preferably live) in the bottle and place it at the bottom of the tank. Then wait until your...
With my Copella (compta I think) I found that aggression was actually much less in a smaller group than when their numbers increased. I started with 6, they bred and at one point I had over 20, by this time they were in a 120cm long tank, densely planted, but the aggression got much worse, they...
I agree they are baby Echinodorus plants, I have had several like that recently in one of my tanks, at first I thought they were going to produce flowers, but maybe as they are submerged they produced these plantlets instead. They do eventually produce small roots but not for quite a while.
According to many sources Cyanobacteria seems to be associated with low nitrates or maybe a high phosphate to nitrate ratio. I have had outbreaks occasionally, always when nitrates have been close to zero. I once seemed to cure it by adding almond leaves, but on another occasion this didn’t...
Sorry I only just saw this post, I did not get a notification...
Well, I am not an expert on these, but I have read quite a bit about dwarf pikes since I acquired some a while back. Mine look very similar to yours and were identified as Crenicichla cf nothopthalmus sp. Orinoco on another forum...
Well yes, there is a degree of variability that may depend on various factors. In Belize for example Cryptoheros spilurus usually spawned in quite deep holes in the bank (often old kingfisher nests) but sometimes just dug pits in the substrate. And I was thinking of convict cichlids, they...
It is an interesting thought. However, there are many other cichlids that are monogamous but breed in caves - eg Amatitlania, Cryptoheros, the pike cichlids (that aren't all Crenicichla now), maybe Guianacara? (conflicting reports on these as to whether they are monogamous or polygynous). There...
Very nice footage of those dwarf pikes! I like those Below Water videos, and was surprised as I had not found that one before. They do look similar to mine, though my females only have 2 dorsal ocelli, not sure if this is variable.
