View attachment 1520995Ok I got my Dino bichir back in March when he was 3”. I have him in a 3’x18”x18” tank by himself. Saturday night I noticed he was freaking out bad, panicking frantically.Normally I do a quarter water change every1-2 weeks but this time I let it go a month without changing the water so I did a 50% water change and cleaned the filter. I did talk to a specialist who said I shouldn’t have cleaned the filter at the same time because I got rid of thegood bacteria. Also said my nitrates were high. My filter was going out nd not creating enough air. I got a new replacement filter & air pump. I added the tank stabilizer & nitrate padding into filter to get nitrates lower. He has calmed down a lot but still doesn’t seem like his normal self. I noticed the slight color change on his tail and I’m wondering if this is something I need to worry about and how to address the problem. I’ve been using a tank stabilizer per directions on bottle & I have jungle aquarium salt to reduce stress but I’m wondering is there anything else I can do. People keep asking about his slime coat but I don’t know how to tell just by looking at him. Please help.
