Raphael In Trouble

[Shovelnose]

I had a Hara Jerdoni and a Platydoras Costatus (for over 3 months) in a 2 foot tank with a sand,rocks and drift wood set up. The filtration was through a Sobo Sponge Filter that pumped out 600 litres and hour.They were fed Blood Worms,Shrimp and Algae wafers. I added a pair of Tiger / Bengali Loaches. (2 Weeks Ago)

A few days later they started competing with the Raphael for space and he stopped eating. So I got another 2 footer with the same specifications set up and shifted the Raphael and the Jerdoni into it. The day before yesterday, I found the Raphael wriggling along the top of the tank. She seemed to be in great pain and was swimming around the filter. So I put my hand in the water to check the temperature and received a shock. Faulty filter I guess. I immediately switched off the filter. On examining I found she had deep red blotches and some dry white patches under and around her fins and near her eyes. Sorry for the quality but I didn wanna use flash and stress her further.

The Jerdoni is perfectly alright and is eating normally. The last water change was 3 days ago and the other tanks that got the water change seem fine. Now theoretically she couldn have been electrocuted. So what could be wrong with her?????????????????

Have you checked your ammonia levels, if the tank has only been set up a couple of weeks then it may not be established and I have had raphaels that showed signs of ammonia posioning long before other fish in the tank suffered from it. Although you have been doing water changes you may not be doing enough to significantly lower the ammonia. The red blotches/patchs could be "chemical burns" around these more sensitive areas.

Haven checked the levels yet. About the water changes, since it is only a 2 footer , I make sure atleast an 80-90% water change occurs every week which I guess is decent enough. But the fact that they show signs of poisoning earlier than others is something I didn know man. Thanks for mentioning it. Il check levels asap.But truth is I would be extremely surprised if that were the case cos I have fish that generate copious amounts of waste in other tanks and they re quite happy with 80%-90% water changes. The Raphael and the Jerdoni on the other hand don generate that much as far as I can see.

All levels look good. Temp is around 26C. There has been a drop in the outside temperature especially in the nights though if that counts too. Food still goes unheeded and the Jerdoni s doing great too.

She s trying to jump out now quite frantically.Swims around very irregularly and when she does swim she scrapes her self on the subsrate.Possible skin infection here maybe???
