Nice jungle you have there! I like the thicket of Java fern. Could we possibly see closeups of the residents? I'd like to see your betta and baby snails :)
As far as I'm aware, bristlenose plecos and otocinclus don't eat hair algae; they do eat fine green algae that grows in a thin film on tank glass, decorations, etc. I say physically remove the hair algae and keep your nitrate level low to deter hair algae from growing back.
The crossbar helps absorb the stress put on the glass from the weight of the water. Once the crossbar breaks, your tank glass is susceptable to bowing, which can create cracks/leaks. This scenario won't necessarily be immediate, but I would start researching ways to replace the crossbar now...
Actually, there are hardly any mom and pop stores in Atl. now; I should know, I live outside the perimeter. :)
The few m & p stores left are pretty much salt only, doubt they'd take in freshwater fish, esp. common ones.
Kissing gouramis will definitely eat any adult and juvenile shrimp in their tank, so no, they're not compatible. Keep in mind that in general, any fish or shrimp small enough to fit in another fish's mouth will end up exactly there. What other fish are in your friend's tank?
Sorry for assuming the 3g was bare, but I would still leave the fry in the 6g. You can always dump some of the greenwater into the 6g for feeding. I just think the 6 would have a more stable bacteria colony to keep ammonia and nitrites at 0.
Agreed that the parents should be moved over. Your 6g is most likely a stable, mature environment that the fry would do better in over a newly set up tank.
What kind of killies?
Snails like mystery, nerite and pond snails are scavengers and if they are omnivorous, will eat decaying fish or shrimp. Pretty sure your shrimp were eaten by your mystery snails. Although red cherry shrimp are hardy compared to other ornamental shrimp, they are not good candidates for a brand...
You didn't mention dwarf puffers, another member did. I was correcting false information, whether it came from you or someone else. The last thing you want is to start back out in the hobby with misinformation.
Although much of what I've learned about this hobby has come from books and...
