    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    They came from Ray Blackburn who I think got them from Tom. Are yours wild? These are F1.

    Hyphessobrycon sp. Red-Blue Peru

    Muy bueno, ha ha. My tenses are not great and I have a lot of vocabulary missing. I can often work things out when it is written though.

    Low-flow and no-flow Apistogramma biotope tanks

    That was a great read; thanks for sharing. Nice to see the kitchen worktop put to good use! Have you experimented using house plants like Epipremnum or Spathyphyllum?

    Hyphessobrycon sp. Red-Blue Peru

    Well, Ian Fuller is talking at PDAS next monthly meeting I think. Hablo un poquito Espanol. En mi collegio, estudio Espanol para cinco anos. Tengo un GCSE en Espanol. Pero no estudio Espanol hasta veinti dos anos. Mi Espanol no es bueno. Donde estan las apistogrammas?

    Gold tetra conundrum

    Good find. I'm glad my MSc in Parasitology has been useful for something.

    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    Well this is an interesting read on the train on the way to my Aquarist Society meeting in Preston! Just to throw more into the mix; epigenetics! It would be interesting to find out which characteristics are influenced by the environment or stresses, and then affect methylation of DNA; creating...

    Gold tetra conundrum

    I'm not even allowed more fish tanks so she'd never buy this. Would be cool to run some experiments on this though. You could also use PCR on fish tissue samples to identify parasite species.

    Gold tetra conundrum

    I'll probably never find out, but who knows? Diplostomum are found in the eyes of fish, in theory, reducing the light in the eye and making them swimcloser to the surface/affect vision, whichmeans they are more likely to be eaten by herons, etc. Toxoplasmosis infection in rats also seems to...

    Gold tetra conundrum

    I would be very surprised if this wasn't the case. The claim is thst it's a trematode (a type of flatworm known as a fluke). The adult stage is in piscivorous birds and they reproduce in the bird's intestines. The parasite eggs enter the water in bird faeces when the bird defaecates and hatch...

    Gold tetra conundrum

    Does anyone have a copy of the original paper that describes this? I think it was by Gery and in TFH. There's a Zarske paper, describing H. filamentosus which shows a few fish in goldform and has an image of what claims to be the trematode metacercaria encysted in the flesh, surrounded with...

    Gold tetra conundrum

    OK, so I haave two different species of tetra, both purchased as gold tetras some time ago. I currently have two fry from one of the species (which of course are silver coloured!). I'm trying to establish the species that I have. I think one is H. rodwayi, but I don't know what the other is...
