Lonely Opaline Gourami -_-

[agusf]

Hello,


Recently my tank (120 liter) has been undergoing some very unfortunate events,
including the death of my female opaline gourami and 3 of my 5 oto catfish.

Rest in peace my beloved fish

luckily enough though my male opaline gourami,
as well as 2/2 kribensis (male/female)
4/4 swordtail (1male/3female)
1/3 amano shrimp
and 1/1 bn plec
all survived.
I was just wondering, Will my male opaline gourami be too lonely on his own from now on?
another general question is Im looking for a quiet way to aerate my tank for my amano shrimp.
meaning no air pump, ive tried that, and no filter ripping surface of water.
Ive heard that if you put a stone or rock you found from a stream, a "live" rock,
it will aerate your tank, or else you can put lots of plants?
thankyou.

problem solved, although in a horrific way.
decided to buy another female, actually was a male,
they fought, took them back both to shop next day

Sorry to hear of the turn of events

Just got to start slowly stocking the tank back up, I'd recommend testing your water before hand, and maybe leaving it for a few weeks to make sure whatever it was has finished it's destructive path.
