Nothing can offer a more complete nutrient profile, higher protein density in this digestible of a package. Today, we feed pellet foods from Nutramar in some percentage to the vast majority of the fish we house. The increase in quality of both flake and pellet foods has increased dramatically in the last 15 years. That being said, today's hobbyists don't have to rely on live and frozen foods as heavily to get their fish and inverts a healthy, varied diet.
In our opinion, this is still good practice as not having these foods available means that aquarists have to rely on bait shops for live food and the history of those foods isn't tracked in the same way. Every aquarium store you went into had feeder goldfish, feeder guppies, ghost shrimp, tubifex worms, meal worms, red worms, black worms, earthworms and the list goes on. Tubifex worm are often used as a live food for fish, especially tropical fish and certain other freshwater species.There was a time (not a long time ago, in a galaxy far, far away) but right here, where feeding live foods was very commonplace and the quality of that food was rarely thought about. Contractile heart is found in the 8th segment. Clitellum is formed in the 11th and 12th segments.Ħ. Setae Forked and hair-like in dorsal bundles and only forked in Ventral bundles.ĥ.
Each body segment except the last few are provided with four bundles of setae on the dorsal and ventral sides.ģ. Tubifex is a small slender worm, measuring about 4 cm in length and reddish in color.Ģ. The animal lives in tubes made up of mud and minerals glued together by mucin.ġ. Habit and Habitat: Tubifex is a fresh water form, occurs in patches on the muddy bottom in the freshwater ponds and lakes. Arenicola is generally used as bait in fishing.Īrenicola can be beneficial by negatively impacting the population of small rodents and insects. Posterior region or post branchial region is much thinner consisting of a variable number of segments devoid of parapodia setae and gills.Ĩ. Middle region or branchial region comprises thirteen segments bearing parapodia and branched gills.ĥ. Body is divisible into three regions, anterior middle and posterior.Ĥ. Body is stout, elongated, cylindrical worm- like measuring up to 20 to 25 cm in length and brownish or greenish in color.ģ. Arenicola is commonly known as lug warm or lobe-worm.Ģ. It is found in Mediterranean and European shores.ġ. Habit and Habitat: Arenicola is a marine worm that lives in U-shaped burrows of sand and mucus. Distribution: Arenicola is distributed in Europe and the U.S.A.
