That gives me a lot of insight. If we eliminate tankmates out of this discussion, and just look at how a betta would do in a deep tank, this lets me know that they can do fine in a deeper tank.Lucy said:Will had a 60g to himself and he did great.
It has worked for quite a few people in the past. Bettas particularly like leafy plants that spread out, like wistera.Meenu said:That gives me a lot of insight.

I know that I've read that if they are in too-deep water, they can drown if they can't reach the top (weakened for whatever reason, so can't swim well). So you can keep a betta in a deep tank, put in plants that are tall and broad-leaved for the betta to rest on if he needs it, and it should be fine, then? Or am I missing something?

No it isn't. There are freshwater catfish that need to keep moving, too. And not all sharks need to remain moving. Scientists have found that many of them can actively move water across their gills.Jaysee said:Fish drowning....thats like an oxymoron. I mean, salt water sharks can drown if they are immobilized, but that's unique to sharks.
You're missing horizontal swim space if you're refering to something like a hex or tubular shaped tank.Meenu said:this lets me know that they can do fine in a deeper tank.
Some bettas do grow fins that are too heavy for their little bodies. I would think this is more of a breeding thing than evolution.Meenu said:So his fins grew long enough that they became too heavy for him to swim well?
Yep. But the individuals of betta splendens that we buy at the petstore have a lot of genetic traits that have nothing to do with natural selection. They've been purposefully bred for larger tails, fuller finnage, etc... In some individuals, these traits go too far. Also, in the case of bettas, it's possible for a fish to be stunted by being kept with his brothers for too long. Sometimes, the fins keep growing.Meenu said:Hmm... interesting. So his fins grew long enough that they became too heavy for him to swim well? Very inefficient from an evolutionary perspective.
There are a few that can, like nurse sharks, but they are the exception not the norm.sirdarksol said:No it isn't. There are freshwater catfish that need to keep moving, too. And not all sharks need to remain moving. Scientists have found that many of them can actively move water across their gills.
Anyway, because of the labyrinth organ, bettas and other anabantoids need to be able to reach the surface, or they will eventually drown.
I don't know why we say deep tanks are fine for gouramis but not bettas. It's an interesting issue, to me at least. But from what Lucy posted about MM's betta in a 60, and SDS's statement that people have done it, I imagine that unless the betta is weak from disease or old age (or heavy finnage), then the depth is probably okay? And from Lucy's earlier comment, it seems like maybe the advice is given not so much because the depth is an issue, but to discourage tankmates. Although if that's the case, then I think we should just give the real reason along with an explanation.Jaysee said:In the thread that this thread origionated from, it was stated that the tank was too deep for bettas, but no mention of the gouramis the poster has in the tank.
Hmmm. Scientific research says the reverse. A few species have lost the ability to actively pump water over their gills (lamnidae being the biggest example, and the reason it was long-believed that sharks could only breathe by moving), a few species are only capable of respirating via actively pumping water over their gills (primarily bottom-feeding sharks that spend most of their time holding still), and the majority of sharks possess the ability to both actively pump water over their gills and to use ramjet respiration to increase oxygen flow during periods of high activity.Jaysee said:There are a few that can, like nurse sharks, but they are the exception not the norm.
