Betta Fish: Male:Something wrong with his fins now... (*Read on*)?

Question

(*I'm Back-With Another Question*)----Simple & short if you don't feel like reading the below: "Betta had cloud eye, fin rot?, aggressive*."

Ok. Here's the story.
First, my betta had Eye cloud/pop eye. I treated it, and it seems to be going away and his personality is still the same - ever before he was sick (nothing's fazed him, he's still energetic and happy). But - after I finish the treatment - I cleaned the tank as required for the "MELAFIX, Antibacterial Remedy". (cleaned the whole tank - but only changed less than 40% or so of the water).

*Now--He's still energetic, but he's flaring his gills at the two guppies I've had in the tank with him since I bought him <-betta (three months ago <-at the pet store; where I assume he got his illness). *This part of the situation I don't find surprising* When I noticed this, I removed the guppies incase he decided to take a chomp outa' them (two small male guppies - 1/6 the size of him).

I just don't want my betta to loose his fin!

Answer 1

I don't see anything in your post about fin rot or fin damage.

His behaviour doesn't seem out of the ordinary to me for a healthy adult betta. Male bettas in their prime will flare at almost anything, so I really wouldn't worry too much about that, he might chase the guppies a bit, but honestly they are more likely to bite him than for him to bite them.

I assume you are seeing some type of fin damage or you wouldn't be worried about the fin. Please add some details about this to your post.

Answer 2

Huh? Loose his fins? Why would he loose his fins?

But anyways, if you're wondering why the betta is doing this is because he thinks that the guppy males are betta males and is therefore establishing his territory and dominance over them. Unfortunately, you cant/shouldnt have these fish in the same tank because theyre not compatible because they just look too much alike.
