What were your water quality conditions for breeding so everyone can be as lucky as you?

 

[Heidge]

Hi,

Thanks all!

Water conditions are:
temp: 30 C
pH: as low as can it be
total hardness cannot detect in tests...Less than 1
carbonate hardness: also less than 1

Water changes with half deionized water. Just put some peat to give a black tea collouration and lower the pH...

Good luck :wink:

I don't suppose you have a PH and EC meter to give us the readings from do you?

That would be great

Hi Matt,

The pH value I really dont have a test at home that could go for it. The maximum is a azoo test and go only 4.5. So I got to get the value of pH in my lab on a pHmeter.

The value of reading was 4.9 in 22.5C. Must remember that in this aquarium the temperature is up to 30C.

What you mean by EC? Carbonate? I dont understand, sorry :wink:

Good luck,

Electrical Conductivity, measured in micro Siemens

or a TDS meter 'Total Dissolved Solids'

Lots of us use the meters as a way to interpet our water hardness, easier than Kh testing.

Thanks Matt.

But I can't have this measurement right now. Sorry...

See you,

It's OK, I know by the Ph, you have no hardness at all.

Hi I have six Dicrossus in a tank, but i dont know exactly if it is maculatus or filamentosus. I have been searching for photos in the web, but i havent seen a good indicator.

Are you sure yours are maculatus? i though the same but the ones i have have a blue coloration instead of red. It is maybe a population difference?

I want to know more information about this fish (patterns of coloration, behavior, etc) because i have only found some poor information about Dicrossus maculatus (which is endemic from Colombia) and some reviews of rio tapajos species.

Hi Andrespal13,

I know for sure that my Dicrossus is D.maculatus. All have adult sizes and are spawning frequently. I see white eggs but no babies. Probably because the water I use. Got to try again straight RO...

If you wanna know more about them, I write some insigths that I learn from them and read in the net. It is in portuguese here: http://www.aquahobby.org/phpBB2/viewtopic.php?t=13609

About location mine came from brazilian waters of Amazon river. I almost sure they came from Manaus... It is really red comparing with pictures that I see in internet, that are predominating blue ones...

If the link dont work for you, try to register in the aquahobby forum.

Good luck with them!

 

[andrespal13]

Ok thanks i read the information in the link, and i find out that the ones that i have are D. filamentosus.

I want to know if this two species cohabit in the same places (i.e sympatric speciation) or they are found in different locations (allopatric). I know that D. filamentosus cohabits confluence swamps in Rio Negro, Orinoco and also some blackwater tributaries with some species of Lebiasinidae (I have mines with Nannostomus eques), but i havent found the ocurrences of D. maculatus.

Maybe you know more about it. Thanks

Nice fish

 

[Heidge]

Hi Andres,

My D.maculatus came from Santarem, not Manaus. Sorry :lol:

I dont think that these two species live together because the different location atributted to them.

Thinking that, one question came to me: I wonder if could happen cross bredding between these two species. Does anyone notticed that?

See you,

 

[kross]

are the males always that colourful even if it's young? and is the female always that dull with only red ventral fins? Would like to know so that i won't get the wrong fish. Thanks.

With juvenile fish the males & females are very similar and hard to tell apart. On mature fish, males have rows of spots on the tail fin but females do not.
