Looks very similar to our sea robins just the wrong color

Not sure, but it doesn't look like a sea robin to me at all. Sea Robins have more of a skin, like a shark, than scales, at least in NJ they do.

Not a standard sea robin that you normally sea on the reefs. The pectoral fin is smaller and the skin is much different, although it could be some variant of sea robin. This thing looked prehistoric. Check out this page of Florida fishes. It's pretty cool. Florida Fish Species |

Looks like some type of sea robin, but maybe not one of the ones listed in your link. Do you think it could be a pleco, escaped from an aquarium? Don't know if they can survive in salt water though.

Looks like some kind of Pleco to me also. But I am unfamiliar with sea robins. Rag’s

Answer: Vermiculated Sailfin Catfish, Pterygoplichthys disjunctivus
Common in Florida. It's a freshwater fish that most likely got expelled through a spillway into the Intracoastal and died from dehydration in saltwater.
Yeah, I know that sounds odd for a fish to die from dehydration, but that's essentially what happens. Saltwater pulls the freshwater from their cells via osmosis. It's the opposite with saltwater fish. If they're immersed in fresh water, their cells will absorb water via osmosis, bloat, and rupture the cell linings. That's actually used as a method to remove external parasites from saltwater aquarium fish during a quarantine before introducing it to the main tank. A short freshwater bath treatment causes parasites to bloat and die in a shorter time than the fish.
And that's your science lesson for the day.

Pterygoplichthys disjunctivus (Weber, 1991)
Common name: Vermiculated Sailfin Catfish
Taxonomy: available through ITIS logo
Identification: Weber (1991, 1992) assigned sailfin catfishes to three genera and described this species as new under the name Liposarcus disjunctivus. Armbruster (1997), after a detailed systematic review, placed the genus Liposarcus into the synonymy of Pterygoplichthys. Weber (1992) provided a key and distinguishing characteristics and photographs of specimens; Armbruster and Page (2006) present a revised key to species in the genus Pterygoplichthys (except P. ambrosettii). Page (1994) also provided a few distinguishing characteristics. Measurements and counts for several Florida specimens were given by Ludlow and Walsh (1991).
The dorsal pattern consists of light spots that become chevrons posteriorly. The abdominal pattern has dark and light vermiculations of equal width (Howells 2005).
Pterygoplichthys and other suckermouth armored catfishes (family Loricariidae) can be distinguished from native North American catfishes (Ictaluridae) by the presence of flexible bony plates (absent in ictalurids) and a ventral suctorial mouth (terminal in ictalurids). Pterygoplichthys is often confused with Hypostomus: these genera can be distinguished by the number of dorsal fin rays (7-8 in Hypostomus vs. 9-14 in Pterygoplichthys).
Size: 70 cm.
Native Range: Tropical America. The Madeira River drainage, Amazon Basin, South America (Weber 1992).

It does say Everglades, which is where it was flushed from. I've seen plenty of them over the years in lakes in western Boca Raton, and in the Hillsboro Canal (Broward / PB border) which has a spillway from the Loxahatchee wetlands.

You're right. I missed the "Florida southeast coast and lake Okeechobee" part.
Case closed!
