Do platy fish have days when they're just more tired? Yesterday afternoon I noticed my platy girl was chilling on her fake plant decoration. I figured she was just going to sleep a little early, but then today she's periodically going into the plant to rest. She shows no signs of disease, and she's eating and swimming around when she's not in the plant, but she is putting her fin down more often than normal (she usually has it up 24/7). My fault, the nitrates were a bit high today (5-10) so I did a 30% wc and I'm going to do another tomorrow. Could she just be feeling the affects of the nitrates? Not really sure what high nitrates cause for symptoms.
