"And Allah has created every animal from water. Of them there are some that creep on their bellies, some that walk on two legs, and some that walk on four..." (24:45) "See they not how Allah originates creation, then repeats it? Truly that is easy for Allah" (29:19). These fish are mainly known as ornamental aquarium fish and noted for their unusual bubble eye. Its completely normal. The bubbles start to grow when they are babies.

The Quran instructs Muslims to "contemplate the wonders of creation" (Quran 3:191). The entire universe, which was created by Allah, follows and obeys His laws. Muslims are encouraged to seek knowledge, explore the universe, and find the "Signs of Allah" in His creation. Allah says: "Behold! In the creation of the heavens and the earth; in the alternation of the night and the day; in the sailing of ships through the ocean, for the profit of mankind; in the rain which Allah sends down from the skies, and the life which He gives therewith to an earth that is dead; in the beasts of all kinds that He scatters through the earth; in the change of the winds, and the clouds which they trail like their slaves between the sky and the earth; here indeed are Signs for a people that are wise" (Quran 2:164) "Do not the unbelievers see that the heavens and the earth were joined together, then We split them apart? And We made from water every living thing " (21:30).
