Looks nice! I'm constantly battling with myself about the bettas some of the large pet stores, but I already have 3. I also have a 29 gallon and just noticed the other day how large it seems from certain angles. How do you like the Seachem Tidal filter?
I like the Tidal filter for a number of reasons:
1. The inside is just a large opening with a basket, so you can put in whatever media you want.
2. It has a skimming function and you can adjust how much water you want to come in from the surface vs lower in the water column.
3. You can adjust the flow.
4. It self primes.
5. It's not noisy.
Cons for me:
1. I originally bought it to have as a secondary filter on the 75G, but because of the lip on the Aqueon 75's, it never sat down all the way, so there was a water fall going into the tank making lots of bubbles which got stuck under plant leaves. I had to stuff the exit with sponges to slow it down.
2. Although it has flow control, I can't make it as slow as much as I would like, so even on the 29G where the lip isn't a problem, I still have to stuff sponges into it.
3. The adjustable intake flow control wheel thingy is low on the filter, under the water, so if you want to adjust it, you have to stick your hand in the water. Also, there is no marking indicating which direction to turn for skimming or under water only intake. I, at least, can't really tell which is selected.
I haven't had any other HOB to compare it to for years, but from what I remember, I would definately recommend the Tidal, especially if you are looking for good flow.
As for the bettas, I hopefully will be able to stick to my plan to never look at them again in these large stores, they look so sad and sometimes are dead. The 2 girls get along fine, so I'm hoping to luck out that a sorority of only 2 will work in this instance. They were such tiny fry when I bought them.
