É um Hypostomus Punctatus. Cascudo comum nas regiões Centro Oeste, Suldeste e Sul do Brasil. Pode chegar a 35 cm, tolera PH entre 6,0 e 7,5, mas prefere PH neutro (7,0).
Alimenta´se de algas, fibra vegetal em decomposição e, ocasionalmente, de outros peixes.
Apenas olhando assim fica difícil saber. Na fonte está um link de um blog que fala sobre as espécies de peixe cascudo, pode ser que encontre.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
