Cichlid Tank With What Looks Like Copepods?

[Alien_spawn]

Hi

I was doing my weekly water change today, and I found on the glass supports some Copepods, now I know from what I read its not harmful for my fish to have these little white fella's in the tank with them in fact its a extra food for them , but what i don't understand is that I thought these only ocurred with salt water tanks?

the tank was orignally a salt water tank about 4 months ago- could it be from there, and if so I thought they couldn't survive in freshwater?

Any advise on this would be helpful

A very confused Cichlid fish owner

Thanks in advance

maybe you could try asking this in the marine section as well.

i have no clue if copepods could survive in FW or not, sorry

There are indeed freshwater species of copepods that are often introduced to aquariums through live plants, so this could be what you're seeing

The strange thing is that I don't have any live plants, so they must have come from when the tank was a marine one 4 months ago- and there was no sign of them even 2 weeks ago- unless their eggs were somewhere in the tank- even so i would have thought sw over to fw would kill them
