That's awesome. i had a T. triacanthus a few years back and it really didn't grab me. He was an adult when I got him and I had him for about 2 years when I had to treat the tank for internal parasites, he apparently had an adverse reaction to general cure. I picked up a little itty bitty a few weeks ago, and he has grabbed me, big time. This little fellow is very entertaining, I even thing he's sweet on this little female red rooster waspfish. hahaha
Click my name and find all threads(or post), and you will find dozens of my venomous creatures through the years. Presently I have a Rhinopias frondosa, a Pterois radiata, 2 Dendrochirus brachypterus , 3 Paracentropogon zonatus , and a T. triacanthus. I'm looking to add either 1 or 2 more dwarf or medium bodied lions to my 90g venom tank and 1 or 2 Caribbean species scorpionfish in a 40g display refugium. I am also considering an Ablabys taenianotus for the refugium, but he may be too floppy for the flow, what do you think.
In regards to feeding dead foods, it's about the content of the dead diet, not the fact that they are eating dead foods. It's essential that they get the proper protein, efa's, minerals, and not get a diet high in thiaminese. For long term success on a dead diet they need "fresh" if possible; fatty fish, shells,bones, and guts of some kind, shell on shrimp with guts and all trimmed of any sharp pieces and cut up small enough, hikari brand silversides as the others may be a variety of fish which contain thiaminese. Try to avoid krill, high in thiaminese, prawns are better than shrimp, as shrimp also contains thiaminese at a lower level but the shells and guts are good. Thiaminese binds B vitamins and is likely the cause of many demise of predatory fish. I just share this because most people keeping these fish on a dead only diet barely keep much longer than a year and a half and most times not even that long. These new enriched chunky predator formula's may be worth a go. I haven't tried them. I grill salmon at least once a week, so I cut a fresh hunk for my preds that will it. I also feed hikari silversides. I only occasionally do shrimp, and yes I will ask the seafood counter for 3 fresh shrimp, or grab a prawn when they have it. I've found my success in feeding live and only supplementing with dead foods.
