Sponge Eating Fish?

Not sure about fish, but I have three emerald crabs going to town on mine lately.

Sea slugs are known to eat sponge. I have 5 emerald crabs and one rock that is covered with pink stringy sponge. The emerald crabs have never dined on the sponge.

If you flip them over and , look for the piece of the carapace that runs from the back to the front of the body. If it's skinny, it's a male, if it's wide, it's a female. I've never heard of a difference between male and female emeralds though.

I've never actually heard of emeralds eating sponges, or any other purely sponge eating fish/etc. Go with nudibranchs! There's some AWESOME nudibranchs out there that ONLY eat sponges and I would kill to have enough sponge in my tank for them to eat.

I promised myself I was done with angel fish a long time ago... no more... ever! I love them but they are coral eaters.

 

I have sponge everywhere... dunno why...

SOME of them WILL eat sponge, but it all depends on the individual fish, and they aren't exclusive eaters, so it's only a chance. You've got an equally good chance of it eating coral as sponges. If you've got enough growth already of the sponge, it should be able to keep one nudi going for quite a while, more if it's a bigger tank.

According to what I've read any sea slug that is a carnivore will eat sponge.

I'd ask the slug keepers which ones are safe for eating sponge in a reef tank http://www.seaslugforum.net/

 

 

what type of nudi branch do you recommend

Flagfin Angelfish

 

Overview

This beautiful fish usually fares poorly in the home aquarium. Chances of keeping it successfully are increased in a reef-type system with plenty of invertebrate-encrusted live rock. Younger specimens tend to acclimate better, and individuals from areas other than the Philippines tend to have greater rates of survival.

 

Family: Pomacanthidae

 

Other common name(s):

 

* Threespot Angelfish

 

Native range:

 

* Indo-West-Pacific

* East Africa

* Samoa

* Southern Japan

* Australia

Feeding

Difficult to feed. This a sponge- and tunicate-eater that often fails to adapt to aquarium fare. Try feeding it sponge-containing frozen angelfish rations, vitamin-enriched brine shrimp, and mysid shrimp as well as plentiful plant material, including frozen preparations for herbivores and marine algae.

Feed at least 3 times a day

 

Aquarium Compatibility

It is usually not overly aggressive toward unrelated species, but may fight with close relatives. Only one should be housed per tank.

Not recommended for the reef aquarium. May nip at sessile invertebrates, including stony and soft corals, and clam mantles

.

Special Care

Can be quite shy at first and should have a choice of good hiding places
