How many gallons is the tank and how many/what types of fish do you have in it? How long has it been set up and is it filtered and heated? Do you use dechlorinator/water conditioner
?
Its a 10 gal 1 dalmation molly,2 glow light tetras,1 black moor goldfish,3 serpae tetras,and albino clawed frog i have a filter heats airpump stone watercondinoer i do weekly 100% water changes and clewan the whole tank
Unfortunately you are going to have a lot more issues with that stocking i'm afraid;
a. The albino frog (which is an African Clawed Frog) has the ability to eat any of those fish- some ACF's will wait until the fish are nice and fat and then massacre the lot. They are carnivorous amphibians with big apetites and can eat some suprisingly large fish in comparsion to their mouth size.
b. Mollys are sociable active fish but a 10gal is too small for one, i would upgrade the tank to a 20gal and then get another 2 female mollys- many fish can display behaviour like agression, even if they are peaceful fish by nature, when kept in the wrong environment and/or stocking. Mollys can grow anything between 3 and 5inchs depending on the variety.
c. Goldfish and tetra's or tetra-sized fish should not be mixed as goldfish will eat anything that fits into their mouth as they grow, and black moors will grow big enough to eat the tetras. The temp requirements for these types of fish is also different, so if you want these fish to grow to their full potential and live healthy happy lives, you should separate the moor from the tetras
.
You should go to the coldwater section to seek more advice on keeping the black moor.
d. Tetras in general need to be in groups of at least 5-6 as they are shoaling fish, and feel stressed when kept in groups too small. You should check out these links;

If you want to keep these fish without behavioral and physical problems problems, i would upgrade your tank to at least a 20gal, rehome a couple of the inhabitants or get them their own suitable tanks (like the frog and black moor) and work on the stocking a lot
. If you leave things too long though, many of the inhabitants will certainly die or be killed.
