I've caught these fellas afew times before with my casting net @ East Coast. Almost 20-40 of them in a single net of about 6-8" long, and also on rod and line, measuring almost 10" in length. As they had recommendation for 100gallon tank, well, not the least surprised, if they want to keep it for breeding?
Tested on myself before (accidentally), poisonous as in other catfish, but still okay, still considered mild when compared to Rabbitfish. Never want to try a Scorpion or Lionfish, they're top of the chart!
