Hello again, Following on from the feed back on my quest to rid my tank of a type of green algae, Several members thought my tank temp too low for Otocinclus ( 69 deg ) I am now going to put in a heater and raise the temp to about 75 deg. Now the question, I have three Akysis they might be vespa not too sure, they are about a inch long come out at night move like a demented rockets hugging the bog wood and bury them selves in the sand. Not the best description. Will they be happy with the lift in temperature?
I find that my Akysis do fine at the higher end of their temperature range, as long as you make sure that you have plenty of dissolved oxygen in the water. I have had mine now for nearly 30 months and they look fine. I keep them in a 50 litre tank that is filtered via; one large air powered corner box filter and one air powered double sponge filter. In the summer months if I find that the ambient temperate of the fish house is getting hard to control and as a result the temperature of their tank goes up to around 28c or above, I introduce a large air stone as well, and take action to reduce the temperature in their tank. I have also found that at the higher temperature they tend to eat more, so I increase my water changing regime, in order to keep my water quality high. Or as an old friend of mine used to say many, many moons ago "keep your water sweet"!
I used to be indecisive but now I am not quite sure.
A big thank you to Sidguppy and Medaka, I will take on board what you have said. Having spent 30 years with Discus and Angels ( In separate tanks ) I thought I would try Asian sub tropical fish, I was convinced I had read that Otocinclus were happy at 68 deg. there you go, I learn something new all the time. Thanks once again Guys. Cheers French47
