my tank is approx 10 litres with 2 glass cats, 6 neons, 2 ghost shrimp.Don't panic; torn fins heal very well.
Have you checked your water? Done a water change? How big is your tank and how many glass cats do you have? They are a very shy and retiring fish and will pine away in a brightly light, fast moving tank with no companions.
yeh i will be getting a 55g in a month.I'd very,very strongly recommend you return the glass cats; they need to be an a shoal of at least six; they can grow to 4"/10cms, so a far too large for your tank.
well I have had the tank for 4 weeks and so far none have died. Every fish looks healthy accept the one mentioned before that like you said can heal.Really you should wait until you have the big tank, before you buy big fish for it; you might well have lost the glass cats in a month![]()

THE tank is 31 cm tall, 32 cm across.Keep you water absoultely nop notch until you get your new tank, you might just get away with it...if you're lucky...but your 10l is way, way, way over-stocked...
