    I got a group of Cobitis paludica from Matt via Dunc and Keith (thanks chaps /sad.gif” style=”vertical-align:middle” emoid=”:(” border=”0″ alt=”sad.gif” /> ), I got them into their own tank and after a few days most had picked up but a couple of the adults were starting to loose weight which I thought was sorted with levimasole. Unfortunately 4 of the juveniles and two adults didn’t pick up and I lost them /ohmy.gif” style=”vertical-align:middle” emoid=”:o” border=”0″ alt=”ohmy.gif” />

    The pics I took when I moved them were rubbish so I took a few more a few days ago when having a sort out in the rivertank:

    Male

    Female and juveniles (from Matt)

    Male and juvenile (from Matt)

    Male front, female right (with juvenile behind) and that is a new youngster on the far left

    Juvenile (from Matt) and new youngster

    Poor image of new youngster

    I have to say that I am very impressed with the growth rate of these youngsters, they seem to be growing by the day

    Bloody hell I think you’re right Mark; we didn’t collect any that small as far as I remember. Dunc?

    Great pics by the way.

    Yeah there is some red in the caudal and it does get brighter when they are eating frozen food as opposed to when they are on dried food.

    Even Joy noticed the size difference straight away so it wasn’t just my eyes /laugh.gif” style=”vertical-align:middle” emoid=”:lol:” border=”0″ alt=”laugh.gif” />

    Btw Mick was supposed to get some of these. Any news?

    Edit: and I’d like to know where they’ve been kept pre-rivertank and water parameters etc. if that’s ok Mark? How long have you had them now? 2 months or summat?

    Great to see them alive and well.

    I was hoping to meet up with Mick in October but things didn’t go to plan but I will be hopefully meeting up with Mick on December 1st at Pier, I will take Mick the remaining adults and juveniles.

    They were kept in a 15 gallon cube up until being moved to the rivertank, the tank had a thin layer of very fine gravel on the bottom with a large clump of Java fern down the right side of the tank, a huge clump of Java moss down the left side and some small pebbles and anubias in the middle.

    Temperature was around 71 – 72 and ph was about 7.4, feeding was a mix of ground dried foods on a morning, bloodworm and/or white midge larvae on an evening, 25% water changes were carried out twice a week.

    Yeah had them for 2 months Matt, according to Kottelat they spawn April to July so I am thinking with so many temperature variations and changes in water parameters in such a short space of time has probably knocked the weaker fish but spurred the other to spawn.

    Like I said before I cant believe the growth rate, they do seem to grow by the day. I have seen this in our own cobitis species though, I have been to rivers in the past in July and that years fry are already around 3/4″ in length.

    Yeah the growth rate doesn’t surprise me given their environment; the Aphanius grow really fast as well and are able to breed at 3 months old. Thanks for the info mate.
