Ok. 3-4 weeks ago i had 2 otocincluses in my tank. There was plenty of algae (brown) and they both ate a ton of it. Then one day one of my otos was severly bulging and i assumed it was full of eggs. Well it was large for about a week and then it just floated up to the top and it was dead. The other oto was fine, eating algae too (green now!) but just last night it too started to bulge. Was my first one constipated from lack of variety in its diet? is that whats happening to this one too? all the other fish are fine. How do i help it? i dont want to lose another fish... thanks
