There are a couple of problems for me.
I have my three tanks in the community creator, and until 10 mins ago I had another three labelled as possible tanks - ie wishful thinking tanks. The fish in those possible tanks are also listed in the signature even though I don't have them and probably never will.
I have just emptied the three possible tanks and find the fish that were in them are still listed.
And another problem. I have fish that aren't in the database so I've had to use the closest match.
The list in my signature as of the time of typing reads:
Siamese fighting fish (male) - yes I do have one
Snails - I have these but not the apple snails that are in the database. I have nerites which are not in the database so I had to substitute apple snails *
Pearl gourami - don't have any. They were in one of the now deleted possible tanks.
Ember tetras - these appear twice even though they are not actually listed in any of my tanks.
Galaxy rasboras - listed twice but I don't have any. I do have them listed in my Main Tank but they are just subsitutes for fish that aren't in the database. In the text I have written, there are Microdevario and ember tetras - these are what I actually have that are in the CC as galaxy rasboras.
Neon tetras - I don't have any. I used to have these in my CC tank as green neon tetras aren't in the database. I removed them last week when the last green neon died aged over 5 years.
Emperor tetra - I used to have some till I part-exed them for pencilfish and changed the entry in the CC
Chain loach - yes I do have these!
Flag cichlids - I've never had any but as Nannacara anomala aren't in the database I substituted these instead. However, they died a couple of months ago so I removed them from my tank in the CC.
Japonica shrimps - I don't have any, they are substituted for cherry shrimps which aren't in the database
Alexrods rasbora - I used to have some but they died and I replaced them with Boraras. Boraras aren't in the database so I left the Alexrods rasboras in the CC as a subtitute
Salt and pepper catfish - yes I have these
Otocinclus - I have these
Cherry barbs - I have these
Chain loach - again. I think I had them listed in Main Tank and one of the possibles which I've now deleted, I assume that's why they are there twice.
Galaxy rasboras - again. See comments above for the first galaxy rasboras and the second chain loach
Golden pencilfish - I have these
Agassizis dwarf cichlid - I have these
So in my case, the fish I have and used to have in the CC are not the fish I actually own. Having the CC list together with the list I have typed myself looks very bad as the two do not agree.
Perhaps giving an option to remove the CC list from the signature would be better. That way it could be automatically displayed for those who have not entered their own info in the signature but could be removed by people, like me, who have.
EDIT
I have just deleted all the fish from my CC tanks. Checking my signature after I did this, I see that a lot of the fish in the CC section have now disappeared, but not all, including some that were in the possible tanks I deleted before typing all this.
* A problem with having apple snails in the database - it has been illegal to import these snails into the EU for several years. It is not illegal to sell them but the only ones you ever see these days are those that have been bred in fishkeepers' tanks.
