Hi folks....

Use the SF knowledgebase regularly but generally only the Practical Fishkeeping forum, however i thought I would spread the goodness around.

 

Anyone keep/have kept Microctenopoma?

I have a small group of ansorgii consisting of 1male, 3 female and a couple still small and unsexed.

 

So far information is limited and they appear to be a rare find, and thanks to their boring brownness as young fish they were overlooked by most buyers.

 

They are doing well in a community tank with soft water and a slightly high pH which will limit breeding opportunities. They eat anything thrown at them - flake, live, even follow the pygmy corys as they lay eggs.

And so far they are being nicely behaved!

 

Now I've just got to figure out how to lower pH for a breeding attempt! :)

Welcome to the forum and nice choice of fish! :) I kept M. ansorgii for a couple of years and they bred several times. The approach used was two pairs in a 50-ish litre tank with an air-powered sponge filter turning over slowly, thick layer of leaf litter and couple of chunks of bogwood with Java fern attached. Obviously wouldn't recommend this for your community tank but a 95% phosphoric acid solution was used to bring the pH down to around 5.0. The males were super-aggressive with one another and all 4 fish constantly had tattered fins but never developed any fungal or other issues, and the behaviour seemed to be part of the courtship ritual. Because of the leaf litter fry would just appear in the tank so nothing special was ever done with the eggs and the bubble nests were simply left in place. The fry were left in with the adults until they reached around 1 cm in length then fished out as and when possible using a very small net so as not to disturb the substrate.

Really must update the species profile on here, it's one that we've still not sorted. Embarassed

Hi.

 

Thanks for the reply and apologies for the delay.

 

I am awaiting a tank exchange at the end of the month, swapping a small salty setup for some empty tanks. Hopefully this will allow a little experimentation.

 

I've been doing more fish watching, as always, and the head count is now 1 confirpmed male, 1 suspected male, 4 females and 1 still too small. ( 1 fish I thought had died reappeared!). So plenty of opportunities to create pairs - but not so many males as to cause mass fights.

My tap water is a big problem being very soft at tds 50pmm(too soft for reliable GH/KH from API tests) but also very alkaline with readings often ph8+ (7.3-9.3). The days of walking in to a shop to buy acid, however, is long gone with only citric acid available. Once I have a suitable setup in place then I will indeed be looking around for phosphoric acid as its been on the shopping list for a while.

 

As things stand only once have I seen any of the fish spend more than a few seconds at the surface, instead they stay firmly rooted to the substrate. Unfortunately as every water change raises pH again its puts a firm lid on the breeding of a number of my fish.

Still not seem any acid around locally so looks like it will be online orders again - but phosphoric or hydrochloric? +/- to each! May just come down to cost/availability.

 

Same breeding problem exists with my Nanochromis transvestitus - they love the soft water,but not so much the high pH.

Unsure about hydrochloric acid, have only ever experimented with the phosphoric stuff.

Have a look at the reply on this thread. Seems vinegar might be an option?
