To investigate whether male common gobies, Pomatoschistus microps (Pisces, Gobiidae), treat their offspring differently depending on confidence of paternity, we conducted an experiment in which randomly chosen males either spawned alone with a female, or with a sneaking male present. Males did not treat their brood differently whether they had experienced sneaking or not. Our estimates of parental care, nest defence against potential egg predators and fanning rate were the same for the two… 

Cannibalize or care? The role of perceived paternity in the sand goby, Pomatoschistus minutus

TLDR
The results suggest that egg-guarding males cannot distinguish between eggs sired by themselves and those sire by other males but are able to react to cues indicating paternity state, and males do not adopt eggs to attract females in P. minutus.

Alternative reproductive tactics and courtship in the common goby

TLDR
Female courtship behaviour may be a cue for a male either to spawn as a nest holder or become a sneaker in the marine common goby Pomatoschistus microps, which could be more important in fish than is known currently.

Effects of a low oxygen environment on parental effort and filial cannibalism in the male sand goby, Pomatoschistus minutus

TLDR
This study strongly suggests that filial cannibalism in male sand gobies represents a strategic life-history decision as an investment in future reproductive success, and is not triggered by a proximate need for food necessary for the male's own survival.

Paternity and paternal effort in the pumpkinseed sunfish

TLDR
The results indicate that male pumpkinseeds do adjust their care in relation to paternity, but the cues used to assess paternity are not clear, and a general decline in parental behavior might explain the lack of adjustment once the eggs hatch.

Parasitic spawning in sand gobies: an experimental assessment of nest-opening size, sneaker male cues, paternity, and filial cannibalism

TLDR
Experimental manipulations of nest openings provided no support for the hypothesis that nest openings serve as physical or visual defense or that sneaker males prefer to parasitize nests with wide openings, and female mating preference was also not influenced by nest-opening size.

Life‐history variation in relation to nest site abundance in males of the freshwater goby Tridentiger brevispinis

TLDR
In nest spawners, the availability of nest sites should strongly affect life-history traits of males through sexual selection, probably through male–male competition for nest sites and female mate choice for larger males.

The importance of sperm competition risk and nest appearance for male behavior and female choice in the sand goby, Pomatoschistus minutus

TLDR
A partial correlation of five traits thought to attract females (nest-opening width, sand volume, male courtship display, displacement fanning, and male size), males that fanned well were found to also build large nests or display intensely, but not both, which indicates that rather than being jacks-of-all-trades, individual males focus on a subset of traits for attracting females.

Determining the level of parental care relating fanning behavior of five species of clownfishes in captivity

TLDR
Relation between body weight and the fecundity, fanning duration and frequency with hatching success are documented and Gradation of dissolved oxygen levels adjacent to the clutch area due to the fanning behavior is discussed.

Brood Size and Offspring Age Affect Risk-Taking and Aggression in Nest-Guarding Common Gobies

TLDR
It is concluded that male common gobies evaluate future reproductive success by using brood age and brood size as cues for making decisions about risk-taking and aggressive behaviour during parental care.

Food access, brood size and filial cannibalism in the fantail darter, Etheostoma flabellare

TLDR
It is concluded that eggs are only partially eaten for energetic reasons, and it is suggested that small egg masses are completely consumed because the costs of caring for a small egg mass may exceed the expected reproductive benefits of a large egg mass.

Female sand gobies gain direct benefits by choosing males with eggs in their nests

TLDR
Female preference for males with eggs in their nests is adaptive, and can be explained by direct benefits, as more surviving offspring are produced.

Reproductive behaviour and ecology of Symphodus (Crenilabrus) Ocellatus, a European wrasse with four types of male behaviour

TLDR
The temperate, gonochoristic wrasse Symphodus ocellatus was studied in the field (Corsica) and the simultaneous occurrence of T-males, satellites and sneakers within a species is compared to a few other examples of diverse taxa.

Confidence of paternity and male parental care: an experimental study in tree swallows

TLDR
Male tree swallows did not reduce their parental effort over a wide range of paternity, and previous studies showed they commit infanticide when their paternity is zero, suggesting that they exhibit a threshold response to decreasing paternity.

Sperm release behaviour and fertilization in the grass goby

TLDR
Nesting males of the grass goby Zosterisessor ophiocephalus showed bouts of upside-down movements while rubbing its genital papilla onto the ceiling of its burrow, which may improve the nest owner's reproductive success against intruders or sneakers.

Male reproductive tactics in the threespine stickleback– an evaluation by DNA fingerprinting

TLDR
A random sample of 17 threespine stickleback nests was analysed using DNA fingerprinting and the guardian male was thought to be the true father of all these fry.

Parent Cannibalism of Offspring and Egg Raiding as a Courtship Strategy

TLDR
Differences among species in the relative importance of filial cannibalism and heterocannibalism may explain patterns of sexual size dimorphism in fish with parental care, where females should prefer larger males as better brood defenders.
