Scrawled Cowfish

[ackee]

You would not think so to look at them but Cowfish on the reef can take off like a rocket, with blinding speed for a short distance. They tend to be very careful. When you approach too close they look like a baseball hit right off the bat, gone instantly.
The best food for small ones, in my experience, are live blackworms. As they get larger they will take small garden worms. Both food are extremely nutritious. They will learn to eat small freshwater snails, useful in keeping their fusiform teeth from growing too large, always a potential problem for larger Trunkfish.
Along with other members of their family of fishes they move fine sand by shooting bursts of water from their mouths, exposing various live food items. They will do this in an aquarium. Fun to watch. Those fusiform teeth allow them to eat pretty much anything that catches their fancy.

Just the other day mine flipped out for no reason and rammed the lid harder than I ever though it could. I thought it might have broke it. One of its horns is a little dented but other than that it is no worse for wear

Very disappointed... I woke up Christmas morning to find my cowfish dead only tank... I have no idea what went wrong... I feed the best food daily (cycloeeze, rod's food, mysis)... he was eating from my hand. All the other fish are fine (purple firefish, firefish, blue stripe pipefish, red scooter, assessors)... nit sure what happened...

Very sorry about your Cowfish. When they are small they tend to be delicate. They are not like most other fishes, able to negotiate their environment with grace and ease, and they also seem to be susceptible to bacterial/fungal problems that, because of their physical structure, are not quickly detected. They also, especially at small sizes, require a lot of food. I mean a LOT of food, and need to eat frequently. They need 'meaty' nutritious foods. Live blackworms have been absolutely indispensable for raising the very small 15 to 30 mm juvenile Cowfish I collect every summer. I believe most of my very young Cowfish/Trunkfish would perish without this highly nutritious food. As it is, even with the best care I can provide, I'd estimate that about 20% die from unknown causes with the first week or two. Their aggressiveness toward each other is certainly a mortality factor for my Cowfish, since I usually have several together in the same aquarium. Their food requirements are, in my experience, much higher than most other fishes. They are intelligent personable creatures, very appealing, but not an easy fish by any means, especially when young.

After some time away and some research, I decide to try again... I ran across a tiny scribbled boxfish... I think I spent more on food than on the fish! I believe it is a female... she is still a little shy... but doing well after long acclimation. Her she is...

Thats a nice boxfish, good luck with her.

Long horns need very large tanks people are not always aware of how large they grow to

 

[Joke]

So sad he did not survive

The scribbled boxfish are by far my fave they also stay small and are quite hardy IMO good luck

You do realize this thread you posted to is almost 4 years old?

These are great fish. I've had dozens of them because I collect them here in NJ in late summer as tiny Gulf Stream strays, most less than an inch long. They are easy to feed, and quite hardy. They become an increasingly nervous fish as they grow larger, and they do grow very large. They have a tendency to take off in bursts of amazing speed and force when startled, bending their horns on the aquarium glass. Size is the biggest problem with these great fish.


There is a photo on my Public Profile of an especially beautiful Scrawled Cowfish that I collected in NJ. It was, when the pic was taken, about 15 months old. After another year had passed I donated it to a local public aquarium. It had gotten too large and too jumpy. You can see the slightly bent horns in the pic. There is another pic of an inch long Scrawled Cowfish on my Public Profile taken 4 months after I collected it from a dock piling in Barnegat Bay. It's sharing a tank with a newly caught Spotted Drum from Panama. The small Cowfish that drift up here on the Gulf Stream all die when the water gets cold in October.

Hi, I'm interested in pulling a seine net with you in nj. I usually go to Long Island and get tropical Drifters. I'm looking for new places to go. Where do yo net the cow fish in NJ?
Thanks Ed

I have seen a sudden influx of these into the lfs lately. One near me got 4 in a month or two. I would have loved to get one but I already have a 10" Longhorn and I have seen how aggressive it got towards a Burrfish I put in the tank. I assume something even closer to its species would be dead meat.

IMO I think it should be pretty similar to a Longhorn. As long as you make sure it can get some food, it does well with most tankmates. I've had mine with a burrfish, wrasse, and angelfish which are all aggressive eaters.

10" cowfish? Wooow, please post a picture.
