Apologies for reviving an old thread. What happened to the hyphessobrycon cf. lowes? Did you find that they turned yellow? I bought 12 three weeks ago (11 remain) and they were labelled as the same. They've retained the silver body colour.
No not so much, but that doesn't surprise me. The Hyphessobrycon genus is large and its systematics remain unresolved. So they're often wrongly labelled by the trade.Did you find that they turned yellow?
