It is found that males with relatively large areas of orange pigmentation had significantly faster and more viable sperm than their less ornamented counterparts, suggesting a possible link between dietary carotenoid intake and sperm quality.
Variation pattern of sperm quality traits in two gobies with alternative mating tactics
The pattern of variation that is found in the investment of sperm numbers and sperm quality in goby territorial and sneaker males, supports the results found in other species of fish with alternative mating tactics, suggesting that ejaculate quality traits are usually not traded off one against the other when ejaculate effort is increased in response to increased levels of sperm competition.

It is shown that cross interactions of sperm and seminal fluid may influence the fertilization success of competing ejaculates with males investing in both sperm and vaginal seminal fluid in response to sperm competition risk.

The black goby, Gobius niger, shows alternative male mating tactics, i.e., parental and sneaker males, and the behavioral response of parental males to the ejaculates of males performing different reproductive tactics is measured.

Reproductive morphology in relation to alternative male reproductive tactics in Scartella cristata
It appears the accessory structures of sneakers are traits developed specifically for a nesting tactic, whereas the gonad of sneakers is simply organized to produce as much sperm as possible.

Ejaculate traits in relation to male body size in the eastern mosquitofish Gambusia holbrooki
No correlation between male body size and either sperm or sperm-bundle traits has been found, evidencing the lack of the theoretically expected trade-off between the investment in characters involved in mate acquisition and the investmentIn ejaculate quality.
No reason to sneak: why males of all sizes can breed in the hole-nesting blenny, Aidablennius sphinx
Abstract. Most blennioid fishes show a resource-based, promiscuous mating system with alternative 'sneaking' mating tactics. The hole-nesting species, Aidablennius sphinx, however, appears to be an…
