Species and sex id ?

Hi all,

Btw a lot of crypts require hard water so one has to be picky about which one goes into the aquarium

Most are all right in soft water, the ones from Sri Lanka are more likely to like harder water. I use mainly Cryptocoryne pontederiifolia and C x willisii.

The only plant you mentioned that i'm not familiar with growth rate is Ceratopteris thalictroides.

It has pretty plastic growth rate, if you feed it plenty it <"grows like wild fire">, but it will subsist on <"petrol fumes">.

cheers Darrel

That reminds me totally off topic but I thought crypt nurii (var rosen?) is suppose to do well in very soft water but none of the ones i've tried in blackwater will grow (i have 100s of them in my tap water aquarium so it is easy enough to pull one to try).

I didn't agree with everything that was said yesterday so i wanted to post the full image. As you can see the tank is not very bright - the only thing that changed between this picture and the previous picture is i added some pearl weed on the left top - when it gets adjusted to the new water chemistry i'll bring it lower and another leaf which i add on regular basis (tuesday was water change day). What i do think the aquarium needs is some higher structure as mentioned and some guppy grass to give a continous low area the fishes can hide. What happens is when i zoom in to take a picture of a fish or small region the camera adjust the brightness - when taking a full shot where the aquarium is 1/4 of the frame the brightness is closer to reality; though i keep the room dim so there is still some amplification.


This is the 2nd darkest aquarium i have - the other one being the one with the group of c. hastatus (which is a 20 long):
