That's called gill curl. And it's caused by bad, or inadequate water parameters. The tank may be too small, the filtering insufficient, or the water changes too small or infrequent. Also your source of water could be the culprit if all else fails. There is some form of stress that is causeing it. It could even be low oxygen levels or too hard of water. Test it. Good luck.

jars are very difficult to be kept with other fish let alone with other jars

many fish don't breed at all in captivity so does it mean that they don't breed at all

That is actually a good question.They will often school in small groups in their breeding season which is in winter.The rest of the year they are solitary.Keeping a colder temp in your tank may help knowing this but I dare say there is more than just water temp that allows this to happen.I keep my comm tank at 23 degrees Celsius/ 73-74 degrees fahrenheit.Some of our water ways get a lot colder than this, especially our dams that have been stocked with these magnificent fish.The big difference is in the wild and as I said earlier, the weaker fish can simply swim away.In aquaria they are more likely destined for battle.KuricX;1922709; said:
