    Wild caught A. Ortegai shyness and hiding

    Hi all, I'll try, but the pH ~ Carbonate ~ CO2 equilibrium is an area I struggle with. You always have the same amount of CO2 dissolved in water, but when you have carbonate buffering some of that buffering is in solution as bicarbonate (HCO3-) or carbonate (CO3--), meaning that you have more...

    Wild caught A. Ortegai shyness and hiding

    Hi all, Yes, I think that is what this plot shows (from the <"UKAPS link">) original at <"https://www.aqion.de/site/159"> <"Fireplace Aquarium | Planted freshwater aquarium blog"> cheers Darrel

    Ivanacara bimaculata eggs

    Hi all, I've not kept these, but if they are like Apistogramma spp. the fry need the food to move ("wriggle response") before they will recognise it as food. I keep <"Banana / Micro worm"> (Panagrellus reduvius / nepenthicola) cultures, they are incredibly low maintenance. If you feed the...

    Wild caught A. Ortegai shyness and hiding

    Hi all, I think it is and it isn't. I've not had a good record with the chemistry of Dissolved Inorganic Carbon (DIC), but I think that: Only a really tiny fraction (0.15%) of the dissolved CO2 becomes <"H2CO3">, which then disassociates into a proton (H+) and bicarbonate ion (HCO3-). Acids...

    Wild caught A. Ortegai shyness and hiding

    Hi all, Don't believe AI. That is incorrect, the amount of CO2 absorbed is dependent on the amount of CO2 in the atmosphere, via Henry's Law. It is entirely independent of the carbonate buffering system. <"Andy Pierce's"> post on UKAPS. Cheers Darrel

    Tank bred Zebra Acara

    Hi all, Unfortunately what you would have to pay for a fish, and what you can sell them for, often don't correlate. You definitely will be able to sell them, but probably not for what they're worth, if that makes sense? It might depend a little bit on where @Pauljr412 lives in the UK, if it...

    Panduro pairing wait or give up

    Hi all, I feed live <"bloodworms"> (and black mosquito larvae) without any issues, but I've visited a lot of <"old style"> sewage works and you get absolutely huge accumulations of blood worms and tubificid true worms in the later stages of wastewater treatment. Because these both contain...

    Panduro pairing wait or give up

    Hi all, Commercially collected Bloodworms (Chironomidae) come from grossly polluted sites, we don't know exactly what the issue is, and you can use Bloodworms you collect form clean water without any issue. cheers Darrel

    Wild caught A. Ortegai shyness and hiding

    Hi all, They are, and I believe they are an important food items for wild Apistogramma. There are hundreds of species of chironomid, including some that occur in oligotrophic condition etc. I do as well. I've been to a number of sewage treatment works, where you get "non-biting midges"...

    my a. elizabeth

    Hi all, I think it is fine, as long as you keep the leaves topped up. I think it is. I rarely see any of my fish, unless I sit in front of the tank and wait. I look at as the fish are living their "natural lives" and that is a good thing. Cheers Darrel

    Starting a firs blackwater aquarium nitrogen cycle

    Hi all, They should be fine. There are, if you go to UKAPS, we've spoken with some of the scientists working on nitrification in aquariums, research linked in to <"https://www.ukaps.org/forum/threads/co2-on-off-during-cycling.77983/post-784913"> If you have "grown in plants" and filter...

    Male cockatoo agression. How to resolve

    Hi all, I'm a floating plant fan, have a look at <"https://www.ukaps.org/forum/threads/what-is-the-%E2%80%9Cduckweed-index%E2%80%9D-all-about.73647/">. I have Water Lettuce (Pistia stratiotes) in the tanks, I just don't use for the Duckweed Index, because <"of its leaf colour">. cheers Darrel

    Male cockatoo agression. How to resolve

    Hi all, <"Magnolia grandiflora"> leaves are perfect for this, they form a complex, interlocking matrix and are very resistant to decomposition <"https://apistogramma.com/forum/threads/leaves-for-apistos.14590/">. Lomariopsis lineata is a fantastic plant (it is actually now my <"moss"> of...

    Dicrossus filamentosus

    Hi all, They've been enjoying the black mosquito larvae and Daphnia diet, and two of the females look to have laid eggs somewhere in the jungle, but I think the water will be too hard for any success. Cheers Darrel

    How to train apistogramma to eat pellet

    Hi all, Bugbites have been the only dried food that my fish have showed much enthusiasm for as well. Cheers Darrel

    c. hastatus problem

    Hi all, I agree with @MacZ , I just ignore anything I read about "pH stability". What I would say is that in very soft water you need some humic compounds, again I don't know exactly the reason. I think most of of these "facts" are written by the vendors of "pH buffers", "remineralising...

    apistogramma agassizii tank mates

    Hi all, Yes, a Monstera and an Epipremnum aureum. I know that all Aroids contain <"raphides and druse">, but I've never had any problem with Anubias, Cryptocoryne, Epipremnum, Spathiphyllum etc. leaves in the tank. Is it specific to Monstera spp.? I know you can eat the ripe fruit. cheers...

    Dicrossus filamentosus

    Hi all, Yes, I think you are right. I'm pretty sure one is a male and two are females, that one looks like another male, and I'm unsure about the fifth one. I'm only going to keep a "pair", I just need to make sure that is a male and a female, not two males. cheers Darrel

    Dicrossus filamentosus

    Hi all, Failed to get all five in the same shot, but it was interesting watching them. They changed markings as they interacted. So three out of five. And the fifth fish again, in the process of going from bar to stripe. Cheers Darrel

    Anybody incorporating AI into their husbandry?

    Hi all, You don't need AI, just listen to what Mike Wise says, Wise by name, wise by nature. Cheers Darrel
