We have 4 Gouramis, have had them well over a month now (tank is only a couple weeks older than that). While have lost the odd neon and Tiger, these guys have been the 'rock' of the community. Never had any problems.....till now. Noticed lastnight one of the blue gouramis was at the bottom on its side not looking the bes. It occasionally perked up and would move.
Expected to wake up this morning to see it dead but no still alive, but again looking listless and not well.
Any ideas on what (i know thats vague there could be 100 problems). Water seems fine, we are on tank supply. The other 3 Goruram's look fine.
