Maybe the different hybrids should have unique names, instead of all just being called "Tidepool Sculpin". Some of them are so similar that I have to get out a magnifying glass to tell if I got a new one.

tide

oh,i was talking about the tode pool part

As for "how do they fit in there", there are several answers I can give here. Fitting in tidepools is not particularly difficult for a small, agile fish like a sculpin. If you're referring to these fish fitting in in-game tanks, they fit in the same way that other fish do. I don't recall these fish expanding in size to fill a container, and I'm nearly certain that they're not liquid or gaseous.

This mod does not differentiate between male and female fish. The two fish that can be seen on the thumbnail are two of the possible patterns you can breed, although there are more than two patterns available.

how do they fit in there?and are they male and female ones?
