I have a 7" red tail catfish and i recently bought a 5" arowana (only a cheap one for £22.50) the fish were fine together for the first two days but the next morning i woke up and the arowana was gone.... He didnt jump out and was not in the filter. would a RTC be able to eat a 5" arowana?
Another problem is the algae on my tank is a slight brown. It is not out of control at all. but when i scrape the glass the algae does not come off... i bought a algae scraper instead of the sponge i was using but it really makes no difference. i could probably scrub the same bit of algae all day and it would not come off with the scraper. and the algae pad takes for ever and i cant reach the back bottom part of the tank with the pad anyway.
Any suggestions on clearing this up? or products you have that clears your algae?
