Do fish see color?

This is a discussion on Do fish see color? within the Beginner Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; --> About 5 years is normal. I don't think there is any way to know how much bad care affected that though....

Yeah see, and these are at least 3 years old. Though I do not wish them to die, I do not wish to add a whole bunch more fish that I am not really into just to please them. I am not entirely convinced that would be good for them anyway as these two do not seem to find any comfort in each other. I would really not be happy if I got a bunch more and these two were either stressed by the addition or died and then I am stuck counting down on other fish.

How do other people handle it when they are wanting to get something new as the tank becomes available. Do you leave one lonely fish until it is gone?
Then begin with a whole new batch of something else?

I was thinking... IF I do decide to keep this tank running and add something else, I could add cories as I would likely have them in the tank with the Betta if that is the way I go or any other fish I chose. That way, at least there wouldn't be just one lonely little fish in there. Oh, I have Oto's too so... guess he won't be entirely alone. If I were to take down that tank, the Otos would just move to the larger tank with all the others. There would be 10 Otos in there.

Just let nature take its course, no sense keeping fish you don't care for.

Agree, if you do not want the species, then leave the existing fish to live out their lives. You could move them to another tank, in order to allow you to do something in the present one, or just leave them until nature calls them. This is what I do when fish groups are depleted through old age deaths or whatever; after a few years it is probably best to leave them.

And i agree with what others have said about the nipping, this species is notorious as nippers. But, different fish in different conditinos can be different than the "norm." And this can go either way, either increasing the aggression or weakening the fish the opposite.

And yes fish see colour, there would be no need for colour on fish if they couldn't.

Byron made a great suggestion, Inge. Do you still have the tank that the tetra were originally housed in? You could just move them there which would allow you to add what you want to your main tank. I'm guessing the few years of poor care knocked some time off their life, so they might not be with you for too much longer.

Also after hearing all this stuff about how mean and nippy guppies can be, I'm not too sure I want them after all. I used to want a nice tank of fancy guppies... but now

all day time animals that have eye sight can see colors ,almost animal see in black and white that is a myth, unless there eyes are vestigial and alost not in used like alot of cave dwelling creatures.
eye capture images with rods and cones and depending on the animal they can see either like red or blue or yellow and blue is the most common since there is alot of green in nature!
the only animals that kinda see in black and white are the nocturnal ones that have no cones or almost no cones, cones are mainly to see during the day and rods are for night vision!

Well, they wouldn't look as pretty in fish tanks if they were not colored.

I don't have the tank they were housed in at their old home, that didn't belong to me. It was a 10 gallon and it didn't even have a decent top or heater or anything. I bought a filter for it because they didn't have that either. Once when I went there I yelled at my sister because the tank water was so brown I could barely see the fish. She blamed my nephew for it. The tank mind you was on a 5 foot tall dresser on the top and my nephew as 7 years old. Really? He should have cleaned it?

Although they are not fish I would have picked I couldn't leave them there. If they are still around after the last of the guppies is gone, I might consider moving them to the other tank. That said, if they do suddenly become fin nippers that could be an issue with the Angels and Gourami. I might just be stuck with them for some time yet. That is fine, while they are here they will have a nice clean tank with lots of plants to swim around or hide in. Their little gills must feel better now.
