Is this spawning behaviour?

Looks like a male and female.

Yep they are breeding. At the end when the male wraps his tail around the female, that is when they shed eggs and sperm.

If you move the adult fish out, there should be babies in a week.

Thanks Colin.
The eggs won’t make it I’m afraid,there are to many barbs about.I was curious,and I’m chuffed it’s barbs spawning instead of corydoras

If you separate the male and female barbs for 5 days, then put a pair in a separate tank, they will breed there and you can move the adult pr out afterwards and rear up the babies.

You can breed them in aquariums or plastic storage containers.

That could be something in the future.
Melon barbs are cracking wee fish and the males are very colourful.

this is such a dumb question but are these coldwater?

 

[Colin_T]

Most barbs are not true cold water, nor are they tropical. Many come from areas where the temperature can drop to 14 or 15C in winter and go up to 25-30C in summer. If you keep them in an aquarium, you can have the heater set on 16-18C and let the temperature rise in summer. This will encourage them to come into breeding condition when the water starts to warm up. Most danios are the same.

Ruby and rosy barbs also colour up well when breeding.

 

[Fishfinder1973]

That would explain it then,as I turned the temperature up a couple of days ago from 20 to 22.

 

[Colin_T]

Yeah that's how a lot of fish farms breed fish too. They keep the fish cool for a few months then jack up the temperature. Corydoras will regularly breed if there is a sudden change in temperature, as will rainbowfish.

Agreed.My corys spawn after water changes when refilling with cooler water.They prefer to lay eggs on the glass,just below the water line.

nice! the temp dropped to like 14 here LOL
how do i keep water cool during summer

 

[itiwhetu]

If you want to try and get a few to survive build some caves out of flat stones around 3-5mm off the ground. The fry will hide under those, and the adults can't get to them.

how do I keep water cool during summer

Air condition the room or house.

Have the lights higher above the tank so the heat they produce does not touch the water.

Try not to have electrical appliances (TV, computer, etc) on in the room because these produce lots of heat.

If it's safe, open the windows at night and let the house cool down, then close the windows and curtains during the day.

If the water doesn't go above 30C (86F) then just leave it. The fish will be fine in 30C for a few months over summer.

i was talking about outdoors...
it gets up to like 100 air temp out here

 

[Colin_T]

Outdoors you want as much water as possible so it doesn't warm up as quickly.

If you have a below ground pond it will remain cooler than an above ground pond because the soil insulates the water from the heat.

Aquariums can be insulated but once they are warm, it takes longer for them to cool.

Keeping them in the shade can help reduce the temperature but if the air temp is high, the water will eventually warm up.
