Hello all! As you may have noticed from my other posts, I have set up a 12 litre paro tank that is actually staying in the 4’s PH this time 🙂 It’s currently in the process of stabilizing, but I am considering – instead of getting another paro species – moving my colony of P ‘sentang’ to this tank as soon as its conductivity stabilizes (the addition of so much new peat granules sent the conductivity shooting up…currently using daily water changes to address that). My question is…would it be safe to move the juvenile P. ‘sentang’ from their about 6 ph, 35-40 microsiemens tank to this about 4.5 ph tank? (The final conductivity has yet to be determined). The three fry in question all hover just above or below a centimeter in size and already look like tiny copies of their parents. Thankx for your replies! (Also…would the more acidic conditions make the adults more eager to spawn? It has been a long time since I have seen the male flash 🙁 )
Basically, it is not a problem to put the animals in a new container which has water values other than those in the container in which they are now living.
My young Paros grow in water, which I mix with tap water and has some 150 to 200 microsiems. So if I translate the bruises I’ll put them in a container which I place in the new aquarium and gradually add small amounts of water from the new container. This process can take up to 2 hours. Only then I leave the Paros in the new container free so they can explore their new environment.
Will make the days a few photos of what you can see how I do it.Thankx! I guess I will move the adults – at least – to the new tank in about a week or two…will be waiting on the fry (I want to check if there are any others in there). PS…I added some leaves to the tank yesterday and the male has responded by obsessively trying to court a female (clearly the reason he wasn’t courting was he had no good cave spots…). I’ve seen a lot of ‘sexy eyes’ and flashing, but no spawn as of yet.
Hi Bernd, why do you put the fry in tap water? Our Black Forest tap water has ec 250 …. that sounds that would be nearly ideal water for rising young Paros ?????
Hi A.J. , that “getting used to the new water” we know with shrimps or with our Paros from trade … sometimes they have an ec of 800 …. (salt added to the water …).
I take then a thin air hose, fill it with water like when I do water change with a bigger one, top end in the prepared water, upper end down in the “old” water with the animals, and check the flow with a clamp, so that drop per drop comes the new water to the animals and from time to time I remove a cup of the “old”water.I give the young animals first into a used aquarium with normal soft water. When they are as large as 1 cm, I add mixed water at each water change. Have determined that the young animals then grow better and no deformation in the fins get. In addition, the water values are simply more stable. So they do not get pure tap water, I try to keep the Microsiems at 150 to 200.
One more thing: if I feed Daphnia they simply live longer, with my normal aquariums with Ph values under 4 are the Daphnia after half an hour, so the young animals always have enough to eat.This discussion needs to be differentiated.
The important point is not the absolute value of the ec or the Microsiemens-number, because this says nothing about the minerals that cause it. The decisive point is calcium, Ca.
Parosphromenus and other typical blackwater organisms are not very tolerant of calcium. They are not accustomed to it; there is nearly no Ca in the tropical waters they live in. This makes the decisive difference to the bulk of our tap waters. Mostly, Ca is the dominant factor in it. In some cases, however, we have a different, a-typical combination of minerals in tap-waters. In some Black Forest regions, for instance, you have a tap water containing very small amounts of calcium.
The conductibility says nothing about the combination of minerals that they contain. Therefore, two waters with the same ec can be composed of quite different minerals. Parosphromenus stand rather high values of Na, because they are biologically used to it, but not of Ca, because they are not accustomed to it at all. (Think of the treatment of some diseases by salt, Na; they stand it very well).They may live in Ca-waters for quite a time, but they age much quicker than in Ca-free waters.
This explains why there are seemingly some contradictions on a water with the same ec. It’s the same ec, but in reality the waters are quite different. The important point is: For Parosphromenus, try to avoid calcium Ca. Slow amounts maybe tolerable, but in most tap waters the amounts are far too high.
True, pure tap water can quickly bring Paros to its limits, so I only use mixed water, with low Ca value. But you have to remember that I partly 30 30 animals in 30 L water pull up, yes have only small aquariums, since it is already very important that a certain water stability is given. So always well weigh whether it is absolutely necessary. For at any time this process must be reversed, at the latest when one wants to breed and this always means an immense stress for the animals.
