What kind of hot pink eggs are these?
Those appear to be the eggs of a species of apple snail in the genus Pomacea, probably the introduced invasive golden apple snail (Pomacea canaliculata), but there are at least two other candidates1,2.
You can learn more about this species and the problems it causes from this Columbia University webpage.
For comparison — Figure 3 from &quot;The identity, distribution, and impacts of non-native apple snails in the continental United States&quot;3.
