Hey everyone. I've lost 4 sunset honey gouramis in the last month and I just recently found a dead spiketail paradisefish caught in the vals. Anyway, everything else in the tank is perfectly healthy including neons and blue rams. For some reason, only gouramis have been dieing. The most aggressive fish in the tank are either yo yo loaches or 3in rainbows. Any ideas what might be killing all the gouramis? The tank is a HEAVILY planted 60 gallon with an aquaclear 300 filter. Thanks for any help. I appreciate it.
