Your source of protein must not rely exclusively on one type of food, you need variety (animal protein from red meat which has Vit B12 without which you would develop anemia and have abnormalities in the nervous system, poultry, and plant protein from beans, lentils etc which have the advantage of being fat free).
Regarding tuna, it's not advisable to eat it on a daily basis because A- it's canned food (preservative materials, too much salt, metal can) and B- tuna is a big fish and big fish accumulate considerable amounts of mercury, which could add up to toxic levels on the long term.
The same applies for canned sardines regarding the downsides of canned food, and these are naturally very high in salt - not so good for your bloop pressure!
Fresh fish twice per week is the golden rule.

Canned tuna may provide a wide range of health benefits, from improving blood vessel function to boosting weight loss. Besides containing high-quality protein, selenium and potassium, canned tuna also possesses omega-3 fatty acids and B vitamins. However, canned tuna consumption might also pose risks.

One of the B vitamins found in canned tuna is niacin, which might maintain high-density lipoprotein, or HDL, cholesterol levels

Although canned tuna has several health benefits, it does contain mercury, a metal that can have adverse effects on the nervous system and brain function light tuna makes a safer option than white tuna because it's low in mercury

for that ,

Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury. (maximum 3 meals )

Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish.
albacore ("white") tuna has more mercury than canned light tuna. So, when choose choose the light one .

On the other hand ,A 100-gram serving of canned sardines contains approximately 0.6 grams of the omega-3 fatty acid ,he combined total would fulfill recommended intake of omega-3 fatty acids for people diagnosed with coronary heart disease.
This amount is about as much omega-3 fatty acids as you would obtain from consuming smelt, chum salmon

so it is a good choice too .
try to make a variety in healthy food in your diet and not to strict only to some evryday as general rule
