Hi there,
I have a figure of 8 puffer which appears to be suddenly blind! About 3 months ago I decided to get a tank going and finally get myself a puffer, I have always wanted one so wanted to get everything right, for about 2 months I did nothing but read anything I could on this and other forums to make sure I could get everything right. Then a month ago after a 5 week cycle I got my puffer. For the first 3 weeks everything was great he seemed happy and well but over the last three days he appears to be blind! On Monday he was fine when I fed him, tuesday sort of didn't notice the snail until it was right in front of his face and this afternoon I got home from work and he was hovering in one corner of the tank against the flow and had no idea I was there. I tried feeding him and nothing, I held the mussel right in front of him and he had no idea it was there, he could smell it as he got excited but couldn't find it.
For the whole time he has been in the tank I have done tests twice a week and they have always been ph 8.0 ammonia 0 nitrites 0 and nitrates around 3-5ppm.
He is in a 20g with a 100w heater and a tetratec ex600 with the flow turned down, I have fed him once a day varying each day between snails, raw prawns, mussels, bloodworms and live shrimp I have always soaked the food in vitamins as well.
He was in freshwater in the lfs so for a week I left him in freshwater then I started raising it to brackish, I am currently at just under 1.002 with a plan do take it to 1.003.
I thought I had done everything right, have I missed something or made a mistake?
Please help ASAP as I'm not sure how long he will last if he isn't eating!
Any help apreciated!
