Guppies loosing chunks of tail - Betta to blame?

Hallo!

Yesterday I noticed my prime guppy had a chunk missing from his tail. Today, two more guppies had chunks missing. They are all swimming fine (thank goodness)

I don't have anything in the tank that they could be ripping it on. Only Java fern and anubias

Could my betta females, now that they are becoming bigger, be mistaking my guppies for male betta and be beating up on them?

Other tank occupants - 2 platy, 2 endlers (wish the betta would eat them) and leopard pleco.

 

Hi

It could be the platies. Keep water clean to prevent infection. I have used seachem stress guard before and my fish healed fast.

 

Tx @dash will do.

Now that you mention the platy - they do seem to have a bit of pms lately. I've noticed a gravit spot in one of them. Maybe she's cranky as a result. Will keep a close eye on them.

 

Just a quick update on my guppies losing their tails.

Found 2 practically without tails and dying when I woke up Saturday morning.

I had already remove the platy to a bigger tank so they turned out not to be the culprits.

I then had to choose between eliminating the Endlers or the Betta Females.

I opted for the endlers since they are real pesky little fellows and I wished the Betta would eat them. Put them in a breeding box.

Have not had any fin nipping or any further deaths. Will continue to monitor the situation and then drown the edlers if it turns out to be them.

 

I do not think it was the endlers. I would hedge my bet on the betta's. Also, just so you know , it is never a good idea to have endlers and guppies in the same tank as they will interbreed.

Don't drown the endlers - donate them to your local pet shop!

I kept the 2 endlers in the breeding net the whole week, nothing happened to my guppies. On friday before I left for the weekend, I took them out and found another tailless guppy this afternoon when I came home. Tail completely destroyed.

Strange as this may seem, I honestly think it's them.

With regards to the crossbreeding, I only have male guppies in the tank. Down to only 2 Neon Blue ones now. Lost really beautiful ones. :cry:
