Did my plant cause the death of a plec?

[AmyKieran]

I had a Nomaphila stricta in my tank that my cichlids shredded. Just before losing 70% of its leaves, i took it out and gave it to my auntie for her tank. She has Plecs and tinfoil barbs.

The plant had been in a day and one of the Plecs died (common plec about 5 inch) all other fish are absolutely fine

Coincidence or my fault?

My tank is fully cycled with no disease/ pests as far as I’m aware

 

[connorlindeman]

i would say coincidence

coincidence.

I have had the plant in my tanks and the fish eat it without any issues.

If a disease was in your tank and got into her tank, it would need more than 24 hours to build up and spread to fish and kill them.

------------------
Get her to check her tank conditioners (pH, ammonia, nitrite, nitrate).

Find out how often she does water changes and gravel cleans.

Get her to do a 75% water change and gravel clean the substrate every day for a week. This will reduce any disease organisms in the water, assuming there is any.
