i give my aquarium a clean a few days ago and there is a 4inch bcrack on the side of the aquarium from the bottom going up a bit, but it hasent cracked on the inside of the tank but on the outside, i have seeled it with all purpose glue, super g;ue and some stong clear celotape but because i cannot afford to buy a new tank or go through with buying a sheet of glass to cilacone it into the otherside of the tank which the shop told me to do because i havent a clue, and i got a new stock about 2 weeks ago and it cost me a bit in money to buy them also what do i do sell the fish because not all of them will fit into my 30L tank or get rid of both the tank and fish becuase i cant afford to uget a new tank and the fish will die in the 30l tank , and also because the water tempreture levels go up and down and at the moment wales are in a bit of a Cold snap and im worried just incase the tank gives in and decide to empty itself all over my livinroom to feed my cat the fish Help im not happy
