My student, while trying to build a photography tank made these images of hybrids involving a female pumpkinseed sunfish. Fish are half-siblings (dam / mother) generated from the same batch of eggs.
All specimans photographed are male. Interesting that some characters of pumpkinseed are obvious in some crosses but not others. Still trying to standardize background and lighting. Hybrid with redear typical in that head profile more similar to redear even among large animals. In contrast with allotetraploid version of pumpkinseed x redear (shown in earlier thread), the diploid shown here does acquire ther black ventral coloration of redear when on the nest.
