For those who do not know this, I have two tanks in my bathroom- a 29 and a 15 gallon. It is possible to observe both tanks with ease either seated on the toilet or from the bathtub. A few days ago I was in the bathroom in the morning and I happened to glance at the 15 gal. It is very heavily planted with a sand bottom and contains some Malaysian driftwood. I holds my breeding colony of Neocaricina davidi- Blue dream variety, a group of 8 while cloud mountain minnows and a fair number of assassin snails. It is filtered with a pair of Aquaclear 100s (aka 20s), one on each end.
I immediately noticed an awful lot of the assassins were on the front and a side glass on one side (the other side is against a wall). A large number of the snails were high up on the glass. I have never seen this before. Some snails maybe, but not lots of them. Because there are a lot of plants in the tank I can see them moving a bit in the filter outputs. But I did not see any plants moving.
When I was able to go over to the tank to check things out I noticed both of the Aquaclears were not running rather than having their return slowed because they were overdue for maint. and a water change. Apparently over night me must have had a power blink and neither of the filters had restarted. Clearly the problem was low oxygen level due to the lack of surface agitation. I immediately got the filters restarted. Some time later everything was back to normal. The snail were no longer on the the glass for the most part. They were back in and in the sand, on some of the plants and some on the sponges I have on all my filter intakes.
All of the fish and shrimp managed to survive as well. I dread to think what might have happened had this not been a heavily planted tank which was putting some oxygen into the water. This tank provides me with 24 or more each of the blue shrimp and assassin snails to put into my fish club's auction at the end end of our month meetings (except for August).
