Upside Down Catfish too agressive
- I recently got an awesome looking upside down catfish in my 55 gal tank. Im now having second thoughts because he is so aggressive towards the other fish in the tank. There is one gold fish (about twice his size), an angle fish, and 2 cichlids. He terrorizes them all, but hasn't killed anyone yet.....

up-side downer
- Had 2 in 20 gal. tank. Loss air flow, 2 dead zebra loaches, thought 2 dead up-siders also two tetras. Put where all dead fish go, first netted nose down on bottom, next went for the one floating on top, belly up (white belly ) and as soon as the net touch him he came alive. First though, we now flushed live cat, with brown loach. Bad day.

great fish
- I have a 10 gallon tank and have had an upside down catfish for about 3 years. I have two glass fish, two rasbora's and two swordtail fish. They have all lived in harmony. My catfish comes out at night and lives in a cave during the day. I have found him floating up near the top of the tank a couple times, but have learned he is ok. He/she has NEVER been aggressive towards any of the other fish. Perhaps because there has always been plenty of food for him to eat. My tank has been around for a long time, so I am able to put plenty of food in without it causing issues to my water quality. My catfish is a joy to watch at night time, and I hope to have him for a long time. Oh, and he is only about 3-4 inches.

do you research!
- upside down cats are a schooling animal. if you don't give them a school to swim in they start to show erratic behavior. make sure you keep them in groups of 3 to 6 and they'll leave everything else alone. and... if your cat is bigger than 5 inches, its not a true upside down cat. it's a hybrid and will surely be a tank serial killer.

You guys are overstocking.
- Mine is in a 65 gallon aquarium by itsewlf and that is a little small. devils need 70 gallons for 1. 1 Oscar needs a 70 gallon aquarium. Just had to say that. Mine does laps around the aquarium. mine is 8 inches long. It is a cool fish.

Scared the crap out of me
- My upside down catfish lying belly up at the bottom of the tank unmoving for like three minutes after I walked in so I think it's dead so I go to get him out using my hand because I don't have a net right as I touch him he scares me and starts doing laps around the tank as usual.but my catfish is kind to his cory cat and two green barb niebors

Synodontis nigriventris are the best
- I bought the real Synodontis Nigriventris that are non-aggressive and have remained the same size (1.5" to 2") for the past 5 years in my 100 gallon tank. They are a joy to watch, when they come out of their hiding spaces, and aid in keeping the tank clean of food that the fish can't get to. They live with neon tetras, glow tetras, zebra danios, bumble bees, mollies, platys, guppies, angels, a dwarf rubber-nosed pleco, and ghost shrimp. No issues with them and definitely hardy fish. Be sure to get the right one as mentioned earlier in the posts and you'll enjoy them. I've seen others at the pet store that were surrendered because of their aggressiveness and size, they looked the similar, but had no white or pale markings, which could explain why they are about 5". They aren't Synodontis Nigriventris, but another kind. Mine are cute little pot-bellied guys that never bother the other fish and are actually playful amongst each other and with my pleco that is 3". Good luck!

Older than 10, bigger than 6"
- My upside-down catfish (not a hybrid) is more than 10 years old and bigger than 6" long. He/she does not eat or bother small fish. During the 10+ years he/she lived in a 10 gallon tank, he/she mostly stayed in his/her cave during the day and came out at night. In the new 38 gallon tank with many companions, he/she really likes the more powerful water filter and usually stays near or under it rather than in the cave. A nice long-term companion.

Black Upside Down Catfish
- I have a Black Upside Down Catfish. He/she is 7 years old. I bought it in Walmart for $6.00. It is the only fish in a 29 gallon tank, does not play well with others. Sleeps all day swims all night. Will only feed at night. I named it Devil.

True vs hybrid Catfish
- It sounds like a lot of folks commenting here have a hybrid upside-down catfish -- true upside down catfish are not very big nor are they aggressive. I bought two of these hybrids and this was not the best - one bullied the other to the point where I had to separate them. These hybrids can be very territorial. Make sure that the fish you buy is a true upside-down catfish.

No problem but not always upside down
- My upside down catfish isn't always upside down. I find this odd because when I saw him at the store all of them were upside down! Then I didn't see him for about a month! Lights on or off! He is becoming a lil more social now and is out at night. Which does make me happier because he is very interesting. He is in a large tank with mostly larger fish that are semi-aggressive. I have another very large catfish in the same 55 gal tank, and that one loves to lay upside down on a large driftwood. Very interesting characters these catfish are!

Ugh
- My upside down cat fish is just too much and I don't understand it's behavior!! It chases after my Pacus and my Red Devil. They don't fight him back. But he continues to chase and harrass them especially at night I am trying to figure out why he is doin this. My fish are in a 30gallon tank
