My Blyxa looked the same way until my fish ate it. Now it doesn't look like anything.
I came up with a clever way of avoiding that for the time being: I have no fish in the tank. Though that's mostly because I just managed to scrape together the money for a filter. But mine's just a bit more than nothing at the moment anyway. All that it's done in the past two weeks is get smaller. Healthier, but smaller. It's annoying me.
I think I'll pick up an eheim tomorrow or the next day. Can't go wrong with one of those. Maybe a fluval, who knows? I need some flow to help with brown algae. And then I'll have to start considering stocking. So many possibilities. But, that's for later.
