Just need alittle help as to some behavior between my two cichlids- they are about 6months old and in a 10-15 gal tank- yes I am hoping to upgrade by Dec- Lately one has been hiding in the Conche shell in there tank- he or she is way up in there- I tilted it so that I could see the fish and it appears to be alive and fine - not sure if the fish is sick or laying eggs? Well now the other fish is hanging out right on the edge- the behavior is just dramatically different- these fish are typically moving about- up at the top waiting for food- I am going to change out 20% of the water tonight- what I have tested everything is within normal ranges- no noticeable illnesses- my husband who has the icthology background thinks they look fine- but I wanted to get some expert advice as to if this is really just typical breeding behavior or should I be trying something else- thanks for any tips
