What this sheet is for
Keep a record of what went into the tank and when, with the adult size that should have been checked before buying.
Who it is for
Fishkeepers, aquascapers and anyone stocking a new tank gradually.
How to use it
- Record the expected adult size — it is the figure most often skipped at purchase.
- Note the source; a run of losses from one shop is worth knowing.
- Record quarantine if you use it.
- Log losses honestly and write what you think caused them.
What is on the sheet
One page, top to bottom:
Printed under the title: What is in the tank, when it went in, where it came from and what became of it.
Research adult size before you buy. No stocking levels or compatibility guidance are printed. What a tank can hold depends on filtration, maintenance, species and adult size — and adult size is the figure most often missed at the point of purchase. Research the species before it goes in the bag.

Questions
How many fish can I keep?
No stocking rule is printed, because the common ones are unreliable and depend on filtration, maintenance, species behaviour and adult size. Research the species before it goes in the bag rather than after.
