mar­tin cre­ated the topic: 640 L aquar­ium for paros ..
Hello, I would like to describe my expe­ri­ence with paros in a quite big 640 Liters aquar­ium.
At the begin­ing I would like to explain one thing — It was not what I planned to do — it’s just hap­pend ..:)

Since three years I had a prob­lem with ood­inum. I don’t know which is the cor­rect name but i dis­cov­ered a lots of very lit­tle white spots on my fishes .. Pre­vi­ously I didn’t had any prob­lems with parosphromenus for almost 3 years . But then it hap­pend. Becouse of this ood­inum I lost a lot of fishes ( for­tu­natelly i spread some quan­tity of fry among Pol­ish aquar­ists before odd­inum came ). Two years ago dur­ing First Inter­na­tional Parosphromenus Meet­ing I pur­chase a 3 parosphromenus species again . But ood­inum came again ( even if I cleaned all of tanks.. etc. )
After a Year I lost them again… I was close to give up on parosphromenus , I didn’t under­stood why it’s hap­pend. 5 yaers ago I breed P. sp. Bin­tan “blue line” in big quan­ti­ties .. P. nagyi and P.linkei also — They brood almost con­stanly ..

Now I couldn’t keep them alive for few months ..

A year ago I was in Aqua­Glaser and When I saw some Paros — I couldn’t pass away — I bought 10 pcs.

But they have a ood­inium again. I tryed a lots of preparates .. with a medium final effect.
When I was with four last paros ( and they were started to have a white spots) I decided … or they will die with­out a weeks or I will do some­thing else and not stan­dard — I decided to put them in a 640 L tank with Biotodoma wavrini and Satanop­erca acu­ti­ceps … I had a loth of sub­merse plant roots on the sur­face , so there was a lot’s of hide­ing places. I didn’t saw them for a long time but now an almost year after — I can tell You — they sur­vive ! :) They grew up ( I added fresh artemia and live glass worm almost every day .) End finaly a week ago I saw a male in breed­ing colours and I saw him with a female inside a plas­tic con­tainer which I added also.. It was such a greate scene — I almost for­got how pretty they are …
In this big auar­ium ph is 4.5 and water is a pure reverse osmotic . At the begin­ing I was wor­ried about tem­per­a­ture — 29.5 C but this is no prob­lem for fishes ..:) — for sure it is a prob­lem for ood­inum :)
Fishes are heal­hty and I will breed them there and prob­a­bly one day I will remove a con­tainer with lar­vae to raise them in a lit­tle bit more con­trol con­di­tions ( 20 L tank…) . I decided also to put a heaters in to my future paro tanks and keep 2728 C there .. Instead of 24 C.
There is no agree­sion between Biotodoma and paros — paros occu­pied a one cor­ner of aquar­ium and they stay there — now I see why even small aquar­ium for paros are ok .. I had never saw paros out­side this cor­ner , even if there are a hide­ing places also in other cor­ners .. I’m happy becouse I saw a two males and two females :) Per­fect setup .. :)
Paros stay close to the water sur­fce ( in a 60 cm aquar­ium deep) — only thing which is not per­c­fect — I can not made any pic­ture of them … but I will sur­vive with it as long as fishes are happy. It seems that paros back to my fish­room and I hope they are back for good ..:)

See You at the II Inter­na­tional Parosphromenus Meet­ing !

Marcin

Nice a story you told us, Marcin, but I have not quite under­stood what the les­son is … Any­way, hope to see you again in Ham­burg this Sep­tem­ber, and the we can talk about it.
I just learned yes­ter­day from Helene that there are only very few final appli­ca­tions com­pared with those we received als pre­lim­i­nary notes some weeks ago. The hotel needs the final num­bers; so I hope that all friends who intended to come will come indeed.

Per­haps the les­son is that there are also other pos­si­bil­i­ties to keep Paros than the tra­di­tional way with small, technic-​free tanks? My small­est tanks are now 54l with Ham­burg math fil­ters. And air pump. .….;-)

with best regards,
Dorothee

“Keep­ing” ist not the point. It’s no news that you can “keep” Paros in nor­mal or big or huge tanks. The whole inten­tion of the Parosphromenus Project is to prop­a­gate the seed of a new think­ing in the aquarum hobby, espe­cially if fish are con­cerned that are threat­ened to extinc­tion by the nearly com­plete destruc­tion of their habi­tats. We do not need such fish for dec­o­ra­tive aquaria.

From an aquar­ist point of view, these fish are not for keep­ing them but for par­tic­i­pat­ing in sus­tain­ing them. The pro­posal to use small tanks is led by the over­all aim to breed them. And a 54 liters tank is still a small tank. Of course, you can breed Paros very well in such tanks. I have noth­ing against them. But you might tend to change less water. And that is not help­ful for black­wa­ter fish or the fight against Ood­inium.

For me, the les­son of Marcin means prob­a­bly: In a huge tank of 640 liters the milieu for Ood­inium is much less favourable than in 10 or 50 liters. But it’s no use­ful rec­om­men­da­tion for most people.

Hello Zwerge and Peter, I thought about what I learned from this les­son .. And the thing is if I was still though “san­dard” I could lose those paros .. For me les­son is — high tem­per­a­ture ( 29C for e.g.) is not bad .. but it can help in case of some dis­ease .. I don’t know why I always thought that paros should be keep in rather low tem­per­a­ture … 24-​25C. Maybe in my con­di­tions 29C is bet­ter ..
Paros are still fine, one male occupy a cave and females swim­ming around it.. But I saw sec­ond male and it was some­thing wrong with his col­lors .. You can see it on the pic­ture . Is this some dis­ease ..? or just he is in some mod .… ( or still too young to show com­plete col­lors..)

@Peter: I don’t want to prop­a­gate nor­mal /​com­mer­cial aquar­is­tics. Of course we should not for­get the weekly water change. (And you’re right, a 640l tank does not invite to do that.)…
I just want to try to give my fish a place where they can live as healthy as pos­si­ble, because a tank is never as good as the real intact habi­tat… even the water — if we have just osmo­sis water — ro — water, we are not as good pre­pared for our fish as some­one who has really good clean rain water or spring water with a low Cal­cium ….

And I see, that Marcin thinks also about that, how he can opti­mise the sit­u­a­tion for his Paros …

@Marcin:
That dark colour­ing I also once had — with Phoeni­cu­rus in a small 25l breed­ing tank with just a „rucksack-​Filter“.
I posted fotos, but nobody could help me with an idea. I just got the con­fir­ma­tion, that it would not be odium…..
I guessed after­wards that per­haps I used too much of „Aquahum“ (even less as Pawel advises in his blackwater-​recipe)….

Dorothee
