Ulvas and enteromorphs
These algae are common on European coasts. They do not last for long in an aquarium,
but are useful as food for marine fish with herbivorous tendencies. The ulvas or
sea lettuces (several species belonging to the Ulva genus) resemble translucent
lettuce leaves. Leaf size: 25-30 cm.
The enteromorphs are filamentous, also translucent, and pale green (Enteromorpha
genus, several species). Size: 40-50 cm. It is worth noting that in the wild Ulvaceae
thrive in areas rich in nitrates.
