The study was conducted to determine the effects of earthworms (L. terrestris) and commercial feeds on the growth and survival of pages Sphenops and X. Helleri at 1% level of probability. Two treatments with three replicates were utilized. Treatment 1, pages Sphenops and X. Helleri was feed L. Terrestris and treatment 2 was fed commercial feeds. Feeding was done twice a day, 9:00 o'clock on the morning ang 4:00 o'clock in the afternoon. Two-group design was utilized as the experimental design of the study and t-test as the statistical treatment in determining its significant difference. The experiment conducted 30 days only. Data was gathered through sampling every 10 days of interval to constantly monitor the length and weight increment of the pages Sphenops X. Helleri. Based on the experiment, treatment pages Sphenops 2 gave the better result of 2.68 cm of length and treatment 1 reached only 1.84 cm. In terms of weight same two treatments gave the best result of 1.73 grams of the weight increment. In terms of survival treatment 2 gave the higher results of 80% and treatment 1 reached only 68.33%. Based on the result using Chi-Square, the computed x² value is 0.54 is less than the tabular value of 3.841. Thus the null hypothesis is accepted proving that there is no significant difference on the survival of pages Sphenops. Based on the result using T-test, in Molly (P.sphenops) the computed t-value of -0.72 cm in terms of length and -0.02 grams in terms of weight are less than the tabular t- value of 9.925. Thus, the null hypothesis is accepted proving on the effects of Earthworm (L. terrestris) and commercial feed on the growth and survival of Molly (P. Sphenops) has no significant difference. In X. Helleri treatment 2 gave the best result of 2.75 cm length increment and treatment 1 reached only 1.99 cm. In weight the same two treatments gave the best result of 1.81 grams of the weight increment. In terms of survival treatments 2 gave the best result of 73.33% and treatment 1 reached only 81.67%. Based on the result using Chi-square, the computed x² value is 0.28 is less than the tabular value of3.841. Thus the null hypothesis is accepted proving that there is no significant difference on the survival of Xiphophorous helleri. X. helleri the computed t-value of 0.97 cm in terms of length and 0 in terms of weight are less than to the tabular t-value of 9.925. Thus, the null hypothesis is accepted proving on the effects of earthworm (L. terrestris) and commercial feeds on the growth and survival of Molly (P. Sphenops) and Swordtail (X.Helleri) has no significant difference. Therefore, L. Terrestris can be used as the alternative feeds for the Molly (P. Sphenops) and Swordtail ( X. Helleri).
