ok lol i had a feeling that scat wouldnt do well in there but it was worth a shot, there off
and yeah after i researched more on the panther goby im taking it off to as 1.) like you said its hard to keep and i want to go real simple with my first brackish and 2.) its poisionous lol
here is my new set up (imo i know im not an expert n any way but if you guys can get more examples of knights eating the bumblebees then ill alter the stocking)
5 mono
6 bumble bees
3 knight gobies
1 F8 puffer
is there anything else i could add?
Personally I still think that that tank will be overstocked with that list - Monos are also big animals (I will probably get a shoal in the future but only when I get a 400l), I also think that the Monos would prefer a higher salinity than the other fish on the list - BBG's, Knights and F8's will all do well at SG1.003 where you would be able to add plants if you still wanted them.
There was somebody on here who was adamant that Knight Gobies should not be mixed with BBG's, maybe you could search for the post but if it was me I wouldn't risk it.
If you do go for a lower salinity system then there is plenty of other fish that would do well and won't grow too big; like Orange chromides or a shoal of halfbeaks or certain species of glassfish.
