Clean Up Crew

I have a dozen Amano shrimp, one juvenile Lemon BN Plec and now have five Rabbit snails, which combined make up the clean up crew in my tank...  It has to be said, that between them, they absolutely removed every shred of algae in the tank superbly...!!!  I suspect it is the Amanos that are the most efficient, but it's hard to know now... 

So, with them having devoured all the algae, the problem now is keeping them all fed...!!!

I would imagine this must be a fairly common "issue", especially with newbies to fish keeping...  So, the Lemon BN Plec will eat red pepper but shows little to no interest in courgette or cucumber - could this be with her (I suspect it's a she - no bristles yet) just being a bambina still and consequently unfamiliar with other veg...?  The shrimp soon mob any veg I pop in the tank and if they happen across it on their travels, so do the Rabbit snails...  The best I have found so far are the recently new to the menu jumbo sized algae wafers - these seem to attract the Amano shrimp in double fast time and even the Lemon BN Plec will munch on them once she realises there's one in there... 

Just curious what you guys n gals feed to your clean up crew after their main objective has been accomplished...?

Thanks Donna... 

I love those little Oto Cats...  I'm pretty much fully stocked with fish now and thus can't really have them, not to mention the lack of algae which wouldn't help with Otos...  Fantastic little fish though...   

I purchased 5 otto's about a month ago now and they are doing really well but the guy at MA said they have been here for over 2 months when i brought them. I also have 8 amano shrimp and god knows how many tangerine tigers as they are breeding along with the assassin snails who have cleared up all my nuisance snails and are also help clearing up any waste food that the shrimps don't get.

My otto's seem to like algae wafers and also the tetra tabimin tablets and join in the free for all with my catfish.
