Many thanks for your replies. I have been a little concerned about those amanos. They are getting big, and boisterous....perhaps i should try them in my other main tank. Another story perhaps....
Meanwhile, the stats on my nano:
30litre
Unheated, so about 23°c
Shirakura red bee sand substrate
Ammonia etc zero across the board.
PH 6.4
TDS 170
KH zero
*edit* Gh is 7
WC 10% per week using my own remineralised RO using GH+, BorneWild Enlive/minerax/bebi and shirakura blackwater.
Feed weekly using 3mm of BorneoWild shrimp Barley.
Light is just a basic fluorescent, 11 hrs a day.
Filter is a simple internal corner unit 250L/h with spray bar, with very fine sponge.
Plants, as I am low tech, are Java and Christmas moss. Moss ball, Java fern. Dwarf hairgrass. Annubis, vallis and water lettuce all appear to be struggling - no doubt as light too low, but want to remain low tech.
Some bits of catappa log.
There are a few hitchhiked snails plus about 20 small Malaysian trumpet snails.
It has been running for about 3 months, with amanos rescued from Gumtree and added about a month in with bees added about 4 weeks ago. All drip acclimatised. All WC dripped in.
The amanos shed regularly, but the bees havent yet...ever.
Don't feel I have run into any issues yet...just impatient perhaps?
Perhaps the bees are too young? Or is my GH too high? Do you think the amanos will stress the bees?
Tanks!
