Hi every­one,

I thought I’d share this video of my paros attempt­ing to spawn.

Unfor­tu­nately these attempts were not suc­cess­ful.

I had to record the reflec­tion off the inside of my tank to get these pic­tures :lol:

Mike, your video does not show a pair of spec. Sen­tang spawn­ing but it’ a video of an attempted spawn­ing. Mostly the first embraces in a cave hap­pen for hours with­out eggs appear­ing, espe­cially in young pairs, but with older ones, too. This is quite nor­mal and is called appar­ent pair­ings or sham pair­ings (Ger­man “Schein­paarun­gen”). Every sequence of pairíngs is intro­duced by such sham pair­ing attempts, but after some time the eggs appear and the male will fer­til­ize them. There­fore, your video is a video of a sequence of nor­mal sham spawn­ings.

How­ever, in your case sub­se­quently there might have been no real spawn­ings at all. There could be two causes: firstly, the pair has no really quiet place, it’s too much dis­tur­bance around them (take the shrimps!). Sec­ondly, there is a sec­ond male around. This is quite a bad thing for nor­mal spaw­ing behav­iour because that is dis­turbed or pre­vented by nec­es­sary antag­o­nis­tic behav­iour of the two males. There­fore I think you will not be suc­cess­ful with this tank resp. its liv­ing com­mu­nity. In tanks that are really crowded by plants it might be dif­fer­ent, but the best method is to iso­late the pair in a small spawn­ing tank with­out any dis­tur­bance. In nature there is dis­tur­bance, too, but with much more space, and that min­i­mizes the disturbance.

Thank you Peter for that insight.

I will try to take your advice on board.

Its been a while since I made this video and cer­tainly I see your point about the dis­tur­bances of the other res­i­dents of the tank.

I’ve since moved the paros to a big­ger tank but I will cer­tainly look into set­ting up a tank for breed­ing so that my court­ing pair can have some peace and quiet.

I think Mike, that you will be rewarded if you do find a nice quiet tank for your pair, — and you have a really good cam­era I think, so if you set things up care­fully and plan a lit­tle you can get really good videoes with­out dis­turb­ing too much. I have also found my cam­era back again, and enjoy mak­ing videoes. Actu­ally I would really like to show you my last video of today (and hope you dont think it bad of me to use your thread :) … and here you can see a pair of linkei’s also maybe like Peter is describ­ing ‘try­ing’. How­ever they have spawned — as you can see — already a few days ago, — but it seemed like today, they tried for long long time, and it really didnt look as if they knew how excatly they should do.

But if you have a cou­ple — that likes each other — in a smaller tank, and set the cave a lit­tle to the back, but not too much, have it so you can see inside the cave, — the one I use seemed to be per­fect for pho­tograph­ing, although maybe not so per­fect as the roof is a bit not even, which means that eggs might slide up, not a good thing, — how­ever they obvi­ously did not.

Of course you have to make sure you do not dis­turb the fishes or scare them, they wont feel com­fort­able enough then, — but you can make them used to the cam­era by hav­ing it stand­ing on some­thing sta­ble in front, — I dont know what its called in eng­lish, but I have a ‘foot’- thing for my cam­era, so it stands there all day in front of the tank, and then all I have to do is push the on but­ton. So theres not much move­ment in front of the tank. It also gives bet­ter images if the cam­era is not hold by hand, but is stand­ing on some­thing firm. Light is a prob­lem, I acu­tally glued a small pocket lamp onto the cam­era :) … and pointed it into the cave, — not a very strong light, that might dis­turb them, but enough to make video.

I am try­ing to fol­low this pair and the eggs until the lar­vaes have gone from the cave.
Here it is … actu­ally I cut it down to at least half the time, they spend so long in and out, try­ing, leav­ing, try­ing again :) ..
They did suc­ceed in the end, — there are some inter­est­ing views towards the end, for those who have the patience to watch that long .. :)

Hi Helene,

Thanks for join­ing in this topic with your amaz­ing video.

I think both you and Peter are right about the need for a sep­a­rate breed­ing tank.

I’m look­ing into how I’m going to do this start­ing with a new home for my shrimp.

I’d like to say some­thing about videos. I think that see­ing the fish behav­iour will beat any descrip­tion or pic­ture. There is so much that can be learned just by watch­ing. I would encour­age all keep­ers to make videos as watch­ing some­one else’s expe­ri­ence pro­vides great per­spec­tive on what you may be doing right or wrong in your own tanks.

So I guess I’d like to chal­lenge peo­ple to share their expe­ri­ences with videos. :cheer:

Helene, this is a great video. The Parosphromenus cf. linkei are look­ing very good. Do you have some pairs you don’t need? :P My eng­lish isn’t very good. Sorry for that ^^
