Received 2 Gulper Catfish from The Wet Spot today and wanted to share my new awesome catfish, along with some information to help anyone considering them in the future! I'll start by saying that they're beautiful fish, perfectly healthy, perfect fins, and I would highly recommend Wet Spot to anyone considering ordering fish.

The gulpers are pretty small, one is about 4" and the other about 3". Since gulpers will obviously eat fish even larger than they are, they'll be in a 40 gallon breeder tank for now, where I expect them to be able to stay for a while due to their slow growth rate. Eventually they'll be moved to a larger tank, maybe a 75 gallon. I have a soft pool filter sand as a substrate, since their skin is very soft. The tank is decorated with a couple pieces of driftwood, and some very tall and long artificial bamboo, that extends long enough to cover most of the surface to dim the light for these nocturnal fish. I may add more floating plants and/or cover up part of the light to make it even more dim, hopefully encouraging more activity during the day. I also put in a relatively weak powerhead, since gulpers like to swim in place against a gentle current. The tank is filtered with an Eheim 2215 canister filter, which is suited for a much bigger tank, to handle the high production of waste from these big eater. Here are a couple pics of the tank, before the cats were in it.

If you're considering getting a gulper catfish, I would highly recommend a light with the blue led night setting. As soon as I turn it on they're out and about, wiggling and swimming against the current.

The big gulper is pretty sedentary with the lights on, hiding under a piece of driftwood. The smaller one usually wiggles in place next to the driftwood and occasionally does a couple laps around the tank. He also is very curious about me when I sit next to the tank, and he'll come to the glass and check me out. They're very unique fish and seem to have distinct personalities. Here are some photos and videos. I'll keep posting on this thread as they grow and when I can show off their epic eating abilities.

Great aqua scape, I recently got a blue led light for my tank I too find it the best way to enjoy my nocturnal/skittish fish. Love the Gulpers their face cracks me up.

Lol
 
thebiggerthebetter thebiggerthebetter I know you have 3 of these guys, did you have trouble getting them to eat when you first got them? Both of mine are acting normal (or as normal as gulpers act) but neither has eaten anything in the 5 days I've had them. The bigger guy sorta puts his lips on the food and then drops it, but that's it. I've tried scallops, shrimp, tilapia. I'm not too concerned yet, as I know this isn't that abnormal for fish designed to eat such big meals, I just know these guys are fairly greedy eaters. Water parameters are good, temp is 79 and Ammo-0, Nitrites-0, Nitrates-5ppm or below. The only thing is that the pH is a little high in my house, at 7.6, but everything I've read says while they prefer lower pH, they're ok in higher. Any help would be appreciated
 
I think mine started the same way - mouthed first, started eating later. I can't say I've had any problem with them starting to take marine baitfish I offer them.

I'd not worry yet. Once it will have been 2-3 weeks, then maybe.

Ok, thanks a lot. I didn't think I should be worried, but I love these guys so I wanted to make sure. Appreciate the help
