The Ista Ceramic Shelter Home is a perfect place for small fish and shrimp to hide. They are bamboo style tubes which make excellent caves for some small fish such as Plecos to breed in. The Shelter Home is three tubes bonded together and are made from high quality ceramic material which makes it very robust and long lasting. To decorate or disguise it you can easily attach some live moss Java Fern or Anubias on to the top. Approximate dimensions 11cm (l) x 11cm (w) x 11cm (h) tube opening size 4.8cm.
