I think the mini tsunami has affected my fish tank too. All the gouramis who often are greedy eaters now refuse to eat. Must be still recovering from the shock waves.
Do you know that in event of a earthquake your fish tank is the first one to crack? I think we should follow Japanese example by keeping tropical fishes in plastic buckets in the bathroom if you live from 3 storeys up. One thing pity the fish which has to put up with looking at your naked body everyday.
