Fish Fanatic
Hi all, hope you can advise!
Have a Rio 240L with, until Friday, the following healthy & happy fish: 1 small angelfish, 7 harlequin rasboras, 8 lemon tetra, 5 platies and 6 panda cories. Ammonia & Nitrate both 0, nitrate 10.
Friday afternoon, I bought 3 more harlequins. 1 died on Saturday morning, mouth completely gone, just a hole! Then 2 more Sunday morning, again mouth gone. All looked fine the night before so whatever's happening, happens fast.
Phoned up the LFS on Monday, she said that something must have attacked them, theirs are all fine etc etc. No more deaths since Sunday and all looked OK so assumed the new ones just had a problem.
This afternoon, 1 more dead harlequin (no symptoms that I could see), 1 missing and yet another is looking dodgy (top lip doesn't look right, the bottom is white and big). All were fine this morning, noticed just a minute ago.
Any ideas what could be causing this? Could something be attacking them? Seems strange as now it's the ones I already had that are having problems. All other fish are absolutely fine!
Many thanks
