the guy in the fish store told me not to clean the algae off the back of the tank, the color means i have a healthy tank. Any thoughts? It is fur like now
Yes, crabs, snails, shrimp, etc can live together. No, it is not the sign of a healthy tank. It means that your water is off. You either have excessive nitrates or phosphates most likey.
Algae is not a good indicator of water quality at all. My tank has perfect water conditions, but if I were to take my turbo snails out, I would have algae all over within two days.
I personally do not remove the algae from the back of the tank or the sides of the tank. It helps remove nutrients in the water and it gives the snails something to dine on.
ps- the reason I say that algae growth is not an indicator water quality is due to the numerous factors that can lead to algae growth. Even having strong metal halide lights on for just 8 hours a day without adequate snails will lead to algae growth.
for a 40 id say
10-12 hermits
maybe 5 nassarius snails
5 mexican turbo snails
and 5 turbos
but i have a 20 so i just about doubled what i have
so dont go on just what im saying
i agree with mudplayer completely. algaes are complicated organisms, in that they tend to indicate that there are too many nutrients in the water, but not always. i personally think it looks messy, so i clean all four sides of my tank

IMO I would stop listening to that guy.
You can have "perfect" water parameters with macros in your tank, because they are consuming the impurities in the water column.
The guy he talked to might be refering to coraline algae (hence "colorfuL"; bad algae is usually brown or green). I'd say that coraline is good to have and I wouldn't scrape it off the back glass.
If you are just getting the green/brown stuff then you should up your cleanup crew some. Don't over-do it or you could overpopulate your tank, reducing food for all the inverts and some will eventually die off. I'd start with a few more for now and add only if it doesn't look like they are doing a proper job.
i think it depends on the cleaners... my LMB wont eat algae once it reaches a certain length, he only eats the young fuzzy stuff, but the crabs dont seem to care.

is it better to get snails or fish that eat algae? I've heard pros and cons on both
In a small tank like a 40 I wouldn't buy a fish just because it eats algae. You can't have that many fish to start with. My 2 favorite fish, the bi-color blenny and the cherub angel happen to love algae so I am lucky.
