+1 on the previous two there, it looks like you have some nice fish here and i have just started fish keeping and omg i love it strait away couldn't give it up for anything, ye you really need to consider getting a new job your box is an absolute jerk if he dose not pay you, you should not do the work, i know its harsh but thats the world we live in, if i don't get paid i won't work, if i won't work then they loose money vicious cycle keep my happy will keep him happy with more money oner the long run if you are in a legit job and its on contract or something like that, then if they haven't paid you and you can prove you done the job I'm sure you could take him to court about it, over here I'm sure thats the case and should be the case in romania as well,
i really really hope you will keep the fish your are doing allot of hard work and congrats for sticking with it this long good luck
EDIT yes there are plastic aquariums out there but they stain yellowy colour allot quicker, most of the commercial aquariums about are plastic tho, it is more expensive tho hard to believe i know but ye more expensive for a small tank like under 1000L but the larger the tank the cheaper it gets with relation to glass
