Aquarium Fish Identification

[Grumpy Old Man]

I’m a very amateur fish keeper / home aquarium keeper and on my last visit to my local aquarium shop the lady owner asked me to look at two fish in an isolation tank at the back of the shop saying “Bad fish, fight everything, Mr David take away” I agreed to take them both away; one was very easy to identify being a very young “Channel Catfish” at about 12cm in length but the other fish I’m struggling to identify, I am hoping there are some far more knowledgeable people than myself who can identify my new “Bad Fish”

Adding Photos

Maybe you intended to include a picture of the fish in question?

All I know  from previously provided information is that the ones  that swim are  fish. The ones that float  are  bait  or  cat treats.

Although the photo's are not clear it looks like a cichlid, not sure if African or South American, aggressive with any fish other than their own kind.

Thank you for your suggestion . . Maybe the “White Cichlids” it better behave itself because it’s in with two “Alligator Gar” and a “Red Tail Catfish”

Anabas testudineus, common name Climbing Perch, not a good community fish,

will eat anything it can get in its mouth,it a Thai fish so you could release it into

water somewhere.

agree with worgeordie, definiteley looks like a climbing perch and a female at that going by the fins, we get them here in the road puddles and gutters after heavy rain(quite a few at that) and flooding so I checked out what they were, I was right into tropical fish years ago. Should also mention these fish  breathe air and can walk on land and they are aggressive

Last few posters are correct. It's a climbing perch.

 

I worked for many years in an aquarium fish shop back in UK...so recognise this species.

 

Have to disagree with posters saying it's an aggressive species.

 

They are good community fish with other species and can also be kept in same species groups.  Just have to make sure they are housed with fish of similar size to them...because they see smaller fish as food. 

 

They are farmed for human food too...so if you so have a insane killer fish you might have it for breakfast on toast.

The photos posted in the first post don't seem to match so why are the colors different? That fish seems to have two dark spots, one in the front and one at the back.

 

The top fin seem to be narrower and smaller than the climbing perch.

The OPs fish is not yet fully grown. It also looks 'stressed' resulting it isn't washed out colour and the top fin is clamped down to its body ...which is typical for a stressed or sick fish. Looking and the water quality I suspect it's not being housed in optimal conditions.

 

If you search for images if this species you will see it varies in colouration a bit.

Regarding cichlids, they will not fight their tank companions if you place then in a populated tank when they are young. Meaning, if they grow up with a set configuration of fish, they will come to accept them as part of the ecosystem. That's not to say an ailing or weak fish will not fall prey, but in my years of experience with these here, that's my assessment. 

 

One thing to remember, aside from aggression, cichlids can get bigger than you think. I bought four Jack Dempseys, which are very blue and cool looking when young. Now, five months later, they are quite big; one in particular. Their color has faded too, but still nice looking fish. They don't bother the other fish they grew up with, mostly barbs, but they are slowing filling up the tank with their size.

I’d like to thank everyone for their suggestions and advise Etc. The “Bad fish” are doing very well . . .
