It perhaps will not come as a big surprise that the hobby sometimes ascribes common names incorrectly to species names. Tangerine Tiger shrimp are a case in point. Tangerine Tiger shrimp are almost universally described in the hobby as Caridina serrata, but actually they are Caridina cantonensis (much more on that below). Does it matter […]

I love my shrimp! It’s great fun watching them zoom happily around the Shrimphaus. The conventional wisdom in the hobby is keep different fancy colour morphs of the same species separate, so they don’t cross-breed and revert to “boring” wild-type colouration, but it is fun to experiment as well and if you’re not too fussed […]
Read more →Statement of Significance Freshwater aquarium shrimp breeding relies on empirical knowledge about which species can interbreed, but quantitative predictions of compatibility remain limited. We used molecular phylogenetics to measure genetic distances between 17 popular aquarium shrimp species and calibrated a breeding compatibility scale using well-documented hybridization outcomes in felids. Phylogenetic distances within Caridina ranged from […]
