Ok so, I have a 55g community/semi aggro tank with:
5 tiger barbs (2 larger 3 small)
4 zebra loaches (small)
2 mollies (large)
3-5 Molly fry (1 adolescent 3-4 babies)(just what I've seen so could be more)
6 Neon Tetra
2 glass Bloodfin Tetra
(large and I know I need more just can't find any local)
5 zebra danios
2 plecos (1 large 1 small)
And I just added about 40 ghost shrimp...
My parameters are all great, tank is planted pretty heavily, roughly 80lbs of rock with LOTS of caves and crevasses. Sand/gravel substrate. HOB filtration running 20g's over. Good water movement, healthy fish.
My largest fish's mouth is just at half the size of the smallest shrimp. But 3-4 of my fry are smaller than that.
It seems my Molly and barbs are curious but flee when the shrimp jump. My loaches don't mess with them but they live 80% of their lives out of sight.
I took the ghost shrimp from a walmart before they even introduced them to death row (why I jumped the gun) so if it turns into an expensive snack, in my mind it's better than them dying at walmart.
Anyone have any thoughts? Anything I should do to protect them? I was thinking about adding more NEW caves that aren't already loach territory. Maybe some small flower pots or some PVC fittings.
