@ Helene: I will try to produce a picture-study of the egg and fry developpment when the paros are spawning and the eggs are fertized…
I think I will post these pictures here…Hi Dorothee,
This would be extremely nice of you I am really sure that these left two are females and I can’t imagine the me being still alive. Even I case I did not look properly enough and the new male might get into trouble, I still got the second tank which I could set up to keep the two apart from each other out of trouble…
hi everybody,
When I found the eggs, they were probably about 6-8 hours old. This was the time when I took the first microscope-pictures. Now, I guess they are over 12 hours old and there should, as deepin peat mentions, be visible blastomers to be found. I was lookign for the eggs but only found that there were about 4 or 5 of them left. I think I can definitely tell now that they have not been fertilised since I could not any of the mentioned charateristics a fertilized egg should have. I comared with older pictures of fertilized Betta coccina eggs I had taken about half a year ago. There, after 10 hours, the blastomer are clearly visible. (The first picture is a B. coccina egg, the blastomers – the first cells of the growing embryo – is the greyish structure around the yolk on the left bottom part) The other pictures I added aer the ones I just took of two of the eggs. Maybe, somebody sees more than I do but I am quite sure there is nothing. Besides this, the fluid around the yolk looks like an emmulsion, not at all clear…
So there is probably no male…Enough of the embryology (a highly interesting subject by the way)…
The behaviour of the two fishes is still rather strange. One (the bigger, a bit larger fish) did some kind of a cave-tour when I came in this evening. She swum in and out of the caves, quickly followed by the second girl. I am really sure that these two must be girls since they both have almost no filament, no blue dots on the side and their caudal fin is of almost no color. I would be really surprised if one of them prooved to be male. Somehow, this larger fish was also really interested in the place where the eggs lay. As mentioned above, most of the eggs have already disappeared. I could, however, not find a nest in one of the three caves (that are all placed in a way that I can easily check them…) I tend to think that one of the females must have lain the eggs. Maybe because of the big waterchange or for another unidentified reason. The two do not show aggressions, They seem to be “playing”. On the two last pictures, you can see the cave-hopper…Hello everybody,
I am pretty much irritated by my paros. I had a look at the tank today morning to see how the two left females are doing. I also arranged a new meeting to get another male from Dorothee.
This morning, as mentioned above, I watched the two females again and was surprised to see something really strange in the front of the tank… Whitish little spots, maybe the size of mustard grain (about 1mm in diametre). Since I have been breeding Bettas and other Fishes as well, I was quickly reminded of the Eggs of Betta. The only strange thing was the fact that these eggs were neither covered, nor did they swim (Lay in the front of the tank in the Peat granules.)
I had to go out for a scouts meeting but when I came back, I ran down the stairs to see wether they were still there or not. Luckily, they were and I got out my microscope and observwed them underneath the lens. They do really resemble to betta eggs. I also checked the Caves and saw one paro swimming out of one. but No nest or something similar. I did not find fetuses or small larvae in the eggs which means, after my experience that these eggs are only a few hours old. The white color is also an indication that they have been fertilized. The yolks of betta eggs are white and I did not find fungi on the eggs. I took a few pictures, The mircoscopic pics are taken with a magnification of 100. Still, the Paros do not show too much of interest on the eggs. I really have no clue where these eggs might come from. They can not be snail eggs because none of the species I keep produces something similar.
What a change… yesterday, I was worrying about what I did wrong and today I think there might have been some spawning. There must be a male though doesnt it? What do you say to the pictures? Could this be a “unusual” nest or what else?Hi all,
@Dorothee: I got a small inside filter that has a completely closed part where the water is sucked in. All around this entry, there is a filter sponge. I dont think this causes much harm…
I will send you an e mail concerning the new date.Hi all,
I just spent one hour searching the Tank. As deepin Peat recpmmended, I Took out all the granules. I changed about 80 percent of the Water to be completely sure. Sadly, I really did not find the missing Male.
Hi dorothee,
sadly, I think he is dead indeed. There was nothing left but the Peat granules. The water is clear… I will check again tomorrow but I think well see each other again earlier than I had expected.thank you helene,
he has not jumped out because the tank is completely covered. I doublechecked all the stuff I took out…Hello all,
I just looked through all the caves but did not find the male. Then, to be sure, I took out all the deco (plants, caves…). Sadly, this confirmed my fear that the male must have died. I only saw the two females. Even after I looked through all the peat granules on the ground, I did not find the body of the fish. I thing the snails must have eaten it. I definitely saw the male the day after I got the paros. But since then… nothing. What surprises me is that I did not find increased NO2/NO3 levels in the tank. I measured all the essential parameters every second day and nothing showed dangerous levels or even significant changes. These are the parameters of the last measurment:
ph: 5.16
EC: 14
NO3: 0.00 mg/l
NO2: 0.00 mg/l
NH4: 0.00 mg/lI use RO water and a few tap water to increase the EC a bit.
The most striking observation is the fact that the females show great colors and no fear at all.
I assume that the male has died from stress only shortly after I put them to the tank. However, I had the three in a tank with the water of dorothees tank and added during 2 hours cups of tank water untill there was a ratio of about 2:1 new:Dorothees water. I dont understand what I ve done wrong and I feel terribly sorry for this loss. It was such a great fish. I had seen him on the pictures of Dorothee and in live before and during the journey.
@helene: In the tank I have one keptang leave which I cut into three pieces because it was just too large… Then there are another 3 small oak leaves. I think thats ok because The ph remains since I put in the paros at about 5,12 – 5,31 depending on time of the day I measure.Hi Dorothee,
OK thats exacly what I feared… I will now have a closer look at the caves and maybe rearrange the whole tank. I hope he is not dead. The male seemed very well prepared for the moving. I mean it was the largest and fittest of the three.
Anxiously waiting for the result…
Hello everyone,
The linkeis seem to be doing well. there is almost no shyness anymore and the pair loves artemia naupliae.
However, I am still wondering where the trird one is. I never saw him feeding… I am now a bit afraid that he might have died… Maybe stress?
Besides this, I am not sure about the sexes of the two curious fishes. I think its m/f but I am not completely sure because they bot show some kind of side dot that is in both cases of the same size. I will attach some pictures… Hopefully someone can help.
Picture 1 is the tank… I didnt clean the glass.
P 2 male?
P 3 the two courious ones.. I think the one on the right is the m because of the “line” in the dorsal fin and the longer ventral fins
P 3 m?Hello all,
Yes, the Paros Now officially (re-)arrived in Switzerland! Though it is only 10 Minutes from the border to France and Germany:)
@Bernd: For me it is probably too early for another species… However I got another 25ltr Tank in which I thought I will put the adult linkeis if they ate the offspring. Actually, since Dorothee told me that her adults do no harm at all to their Babies and I have seen her tanks I might do it the same way. Of course this depends on the circumstances and wether my paros will behave adequately.. Maybe I will then later on get a Second species for this tank… Hopefully, I dare to say.
@Peter: Thank you for arranging that great contact with Dorothee. Sadly I wont bei able to come to the spring meeting of the IGL but I am planing to go to the meeting of the paroproject-members in Hamburg in September.Hi Dorothee,
Yes I see, today they have already showed themselves in the front of the tank and they ate artemia naupliae.
There is one thing that surprises me: I always see two of them together. But somehow I never see the third one. The two seem to have plenty of fun… I am not sure bur I think one of the two is the male. They are still rather small, I think the males coloration will get stronger as time goes by. Is it possible that I dont see the third one? Do paros make pairs of two like cichlids? Or why do they always show in pairs of two?Hi everyone,
finally, i could take some nice pictures of the linkeis.
They have been hiding all day long untill today. When i went to watch the tank, i saw one of the females swimming slowly through the tank. I found another one hiding under the filter.
I did only fed very few micro worms and artemia naupliae the last two days but never saw a fish eating. Today, i fed some micro worms and the female in front finally ate! I am so happy!
I hope you like the pictures!
