Not terrible, but not great either. Clear for lifes are usually under built. Im guessing 1/2” material that should have been 3/4”… you can relieve a bit of the tank pressure by filling it up 3-4” from the top. Looks like typical “stress marks” over years of time. Probably not going to explode or anything. They rarely just let go when made with solvent. If ur worried or want to reinforce it. You can add acrylic rods on the inside seams or tip and pour the tank with weld-on #40. Both ways of reinforcement can make it last another life time for pretty affordable cost.
