Im going on vacation from tomorrow to thursday and i was wondering how you can make sure your fish will be ok. Ijust bought one of those vacation feeders that dissolve and stuff but is there anything else i can do to make sure they wont die. I have a rainbow shark, a tiger barb(one died over vacation last year, the other one was recently bullied to death), 2 peppered corys, a skunk loach, an albino pleco, 2 rosy barbs, a blue gourami, a farlowella, and a leopard danio(other 2 mysteriously disapeared). is there anything else to do to make sure my fish dont die when im gone?
