If you are stressed out about a fish then you can solve the problem easily. There are a few steps to follow to fix the bad fish problems. The first step is to identify the problem. Secondly, you must figure out what to do with the fish. Finally, you must try out the solution to see if it works.
There are many reasons that fish can act up. Some common reasons that fish act up are: dislike of another fish, temperature, the pH of water, sickness, the habitat of the tank and if the fish are spawning or pregnant. These are common problems that fish may have. These problems are not set in stone as the problem but cover a good portion of the problems.
Finding how to fix the problem is the next step. If your fish fight a lot you need to identify which ones are bad and which ones are just trying to live their lives. Once you have found the problem fish you can do a few things. You could remove the fish from the tank and have it isolated in another tank. You could take the fish back and get a different one. You could also give the fish to a new home and someone who will have more success with it.
If the fish are fighting than there are a few solutions. Fist, you need to identify the fish that are causing the problem. If it is only one fish or one type of fish they probably need to be removed from the tank. You could put them in another tank together away from the other fish.
If a group of fish or a few groups of fish are fighting then the problem may take longer to fix. You can remove the first group of fish from the tank and see if the fish are peaceful without that group. Next move the other group of fish to see if the first group is the problem. The group that is the most troublesome must be removed from the tank.
The most common problem with fish that have a problem is that they dislike a different fish. If you find that this is the problem then try just giving the problem the fish away. This will avoid conflict and make life easier.
