My TDS meter measures in ppm which as others have pointed out is the same as mg/l. Press a switch and it changes to read conductivity in µS/cm, as Mike Wise said this is about twice the value of TDS. I can also read temperature in either degrees C or F.
I don't measure every time I do a water...
The orinoco dwarf was previously called C. regani "orinoco" now it is known to be closer to C. notophthalmus, but is a separate species, this is from the article I posted, the one in bold appears to be the species we have:
The type of C. notophthalmus is from the Rio Negro by Manaus and is in...
Here is a paper about Crenicichla species and relationships based on mitochondria DNA analysis. The Orinoco dwarf species is not maned yet but appears to be closest to C. notophthalmus.

I recently got some from Colombia and I believe they are C. cf notophhthalmus sp "Orinoco". They look just like yours. I will have to try and read that link as I have been assuming the ones wit the ocellus are females. But I think I read that the males of this species do not have the extended...
Same here except that I have never stopped giving them bbs. Now they will eat anything! But they still get Artemia and daphnia as well as a homemade food, bug bites tropical and occasionally other dried food as well. I recently got some dwarf pike cichlids, they will not eat dried food, they...
I’d be content with 8 or 10 initially, maybe they would breed in a tank for me!
Lucky…perhaps they will start to become more easily available and less expensive then, fingers crossed!
They don't seem to be very often available, I would love to find some but have never seen them for sale here, and if they did appear they would be fry expensive...... There was actually someone in the US who was breeding them a couple of years ago, on another forum, unfortunately no longer...
Never tried a matten filter, I have canister filters for the larger tanks and top filters (which basically act the same way) for the two smaller ones (though I would prefer canisters on these ideally). I have used sponge filters in a small fry/quarantine tank and use small sponges as pre...
Same here, I use them for a few days, meanwhile some more are getting ready to hatch in the second bottle. I even do this when rearing fry, not only for enrichment. To be honest I am skeptical that only newly hatched ones have nutritional value, they might be best, but after all they have...
I don't know what your hatcher is like, but I have my home made one made set up standing in a plastic container of water which I heat with a small aquarium heater. At my local fish shop they just use a heat lamp over the hatchery. Of course these also use electricity but I am sure not as much...
Of course I agree with this in general, after all the most interesting part of breeding any cichlids is being able to observe their parental care behaviour. In fact the Laetacara case I mentioned is the only time I have ever raised cichlid fry away from the parents. But if someone happens to...
Right, yes the Laetacara had a lot of fry, I only raised 20 the first time and over 40 the second. Most stayed with the parents in the big tank and not surprisingly none of those survived. I once tried keeping just a few in a breeding net in the main tank but that did not work. After raising...
Why is this the case - I have been successful raising Laetacara fry like this, I don't think I lost any of those that I separated from the big tank? They are very small, but perhaps Apistogramma are even smaller and more fragile?
Personally I would rather use smaller tetras or pencilfish, I like diamond tetras but they do get quite big for that size tank and might look out of proportion. They also seem to breed quite easily. If you really want the diamond tetras I’d agree that a larger Apistogramma and that prefers...
I am not sure but personally I wouldn’t want to try that. I would wait until the fry are free swimming and carefully siphon out some of them ( or use a turkey baster) to rear in a separate tank, using water, leaf litter etc.from the main tank in the fry tank. And leave the rest of the fry with...
So sad when this happens. I recently lost a lot of fish in one tank by accidentally filling it, just for a few minutes, with cold water. There was a problem with the water supply to the house, the tubes were slightly blocked but the water was initially coming out at the correct temperature, just...
I thought that as well, I didn't post anything earlier because I wasn't sure if it was cyanobacteria or not, but it does seem to have that sort of colour mixed in. I have occasionally had a little Cyanobacteria, always when nitrates are very low or zero. Once it seemed to disappear when I used...
I have some Echinodorus (not sure what species but they are basic green ones, but not the really big ones) that I planted in a tank with sand substrate, quite low light (often mostly covered with floating plants and stained with Indian almond leaves, so pretty dark, though not technically a...
