Ok this is a first. ALL of the large fish have migrated to the large tank. There are Neons, Glo-lite Neons, Green Neons, Danios and Platy.
All swimming together with a bunch schooling in the center with others flying in and out and zipping around the tank.
For some of the fish its the most active I have seen them in a group and not being so timid.
Also through watching the fish change tanks, its interesting to see how behavioural patterns shift. As a dominent fish leave, others emerge until it returns.
Oh yah, and there are tones of babies, midnights are anout 1/2 - 3/4 of an inch now and the baby orange oens are about 1/4 to 3/8 of and inch. Lots of babies in the bridge, often find them in groups in there.
Due to the distance and height of the water hose, sucking water from one tank to another really restricts the flow of water the filter can pull. So I removed the flexible tubing and put in straight 3/4 piping. It drops the height that the hose sits at making flow slighly stronger. I also reversed the direction of flow making the 5 - 15 gallon filter in the 10 gallon tank do the work. This way the 20-40 filter can filter more water and do that directly in the larger tank which could use it more.
Without being restricted, the 20 -40 moves much more water and I think the fish like the current. As I type this, the fish have settled down a bit after being fed and are now off in their pairs. with 4 of them sitting in the entrance of the bridge in the large tank??? Two being the midnights. Mommy is probably trying to teach Daddy its proper use.
On a sad note, none of the current fish appear to use the tower when its in from what I have seen. The only fish that use to use it all the time has passed not long after his mate died suddenly a few days after being in the tank.
I think if put in a frozen treat, I will work it into the tower as it rises until it melts, maybe this will draw a few in. Nothing like a bit of coaxing.
