Help! I'm looking for a bit of advice. I recently upgraded from a 40l tank to a 120l tank, and the choice to add a few more aggressive natured fish to the new 120l community left me with the decision to leave my male betta in the 40l with an old plec who was just being harassed by a newly adopted angel fish.
However, he was starting to look a bit depressed (as I've seen happen to bettas in the past - not eating much, sitting on bottom, not making bubble nests) so I thought I'd be a mate and give him a couple of girls to play with. Well, only 5 days later after the girls constantly flaring at him and chasing him around, i found him dead at the bottom of the tank with the girls beginning to appreciate his nutritional value!!
So, not to be discouraged, i go out and get Bettaman Mk II - an almost identical looking male - as I'm keen to move on to trying breeding. All has seemed fine for the last two weeks - he integrated well and was making a large bubble nest in a corner of the tank - but I woke up today to find him sitting on the bottom with almost no fins at all! He's not able to swim well at all, and is looking just as depressed as the last guy, so I've isolated him for now but am not holding my hopes out for him!
So what do I do? Get rid of my obviously aggresive females? Get a different coloured male for them? Re-introduce him into the tank and hope they can work out their differences?
Thanks in advance for any suggestions
