did a 25% water change today was my first and my bottom feeders including my sucker fish is acting half crazy have small bubbles on top of tank that was not there prior to water change it's a 55 gallon tropical tank..

Hi my son had to bring home the class room biology pet for x-mas break. we bought this about 2 weeks ago she was very colorful. At school she has a big tank here she has a smaller one. First night we used heating lamp and sand set up like the big tanks and she appeared more pale the next morning so after some on line research we took out the sand and took away heating light put heating pad under half the tank. she is more active today and she is eating fine but she is still looking pale. I have no experience with reptiles so any help would be appreciated please

me and my husband have been married 4 years he has 2 children with an ex girlfriend and she makes my life hell.. well long story short he doesn't lie to me about all he does for her but he omitts the truth and to me that is lieing i told him you don't treat someone you love and respect like that and he flat out said i don't respect you so i asked him to move untill i can get a place of my own for me and the kids. he is coming here everynight to shower and change into work clothes for the next day i havent bothered to follow to see if he is stayin where he says i really dont think he is cheating he is still wearing his wedding ring im not. He still buys anything i want but seems to want to get in and out asap so why not take all his stuff at once and not bother with coming here it breaks my heart everytime i have to watch him leave again, i do love him but i can't live with someone that says they don't respect me we were fighting and i was in the wrong when he said it but i said i was sorry for the stuff i was wrong about and he just acts like he doesn't care he says he stopped respecting me because of my attitude. the only time we ever fight is over his ex .. any idea's on why he is dragging this out instead of just leaving and letting me heal??? why does he still wear his wedding ring??

I know some of the lyrics....say baby i love i you say baby i need you...

Is there any reason to be denied a passport i know certain countries will not allow people into them but does that stop you from getting a passport. My husband is a felon from a crime he committed many years ago. I have heard he won't be allowed in Ireland and a few other places but will he still be issued a passport and if not will the refund all of my money?

to all of you that have helped me i do not take a phycis class agreed to help someone with thier math work and they sent a physics book so please type anything in response and get ya another 2 points i really apperciate all the help from all of you really smart people...
