it's too bad double sword #guppy lines are slowly going extinct in favor of delta types for commercial reasons. people only want to keep and breed what sells the fastest; which are the big pompous fins and 'boring' monocolors.

this young vienna emerald male of my breeding group is an example of what i think is far more interesting than the delta types. in particular, the intense iridophores, multicolors, and more overall mobility unhindered by bulky finnage.

I had a female #guppy with a bright yellow tail drop a few broods. I’ve now noticed one offspring from the first brood with a bent spine, and a couple of them from the second brood as well. Bent spines can be genetic, it can happen during birth, or there could be other reasons. I’m questioning whether I breed any of their siblings, as they may be carriers of the deformity as well. For now we’ll let them grow out.

newest member of my #fishscrub. not the best quality as they're pet store specimen, but some at least manageable for a breeding project

Loving these red guppies and will soon be over-run with their offspring. #aquarist #guppy #guppies #fish #FishKeeping #aquarium #babies

Very interesting paper by Padget et al. (Proc R Soc B) about guppy predator inspection. Theory predicts cooperation should decrease as group size increases, but they found the opposite. I wrote a blog post about it here

For the past 3 months since dropping #medaka, I've been trying several different species, and I think I have finally settled on a favorite: #endlers. They have proven to be incredibly hardy, productive, healthy and beautiful. They remind me so much of #wcmm in form of care and ease of breeding in all aspects (except cold hardiness).

As secondary focus, I'll be heavily invested in WCMM for my pond hobby.

Guppies are a classic example of #parallelevolution but are they really so parallel? An analysis of published #guppy papers by @alexisheckley @AllegraPearce4 @photopidge @ecoevoevoeco @KristaOke
shows low extent of parallelism
