And I mean rescued in the true sense - his owner was going to flush him down the toilet
I've had Arthur for about three weeks now. His previous owner had been keeping him in a very poor community tank with very little cover, a broken filter and no maintenance (the gravel was filthy and the glass covered in algae). The owner had decided that fish-keeping wasn't for him, had sold the tank, and was planning to flush all the inhabitants down the toilet.
Arthur had been sharing space with a golden Gourami, three red-tailed sharks and a couple of others, and was sporting a few injuries from the situation.
One of his gills is permenantly in a flaring position, and the rays on his fins, while apparently intact, are badly mangled and very tatty. Despite this, when I put him in a tank on his own, whe seemed quite healthy and lively.
That's all changed. For roughly the last week, he's seemed very lethargic, and just recently has taken to spending all his time resting on top of the heater.
I've raised the temperature to 82 degrees, and have been treating the water with IAL extract, making daily 50% water changes. Given that he's about twice the size of my own bettas, I realise that it's a possibility that it's simply old age, or that he's succumbing to his injuries, but I need to know if there's anything else I can try?
If it's simply his time, then at least I know that he's had a peaceful last couple of weeks, but I don't want to give up if there's something I can do to help him.
