I have a 75 with a bunch of live rock(80-100lbs) and a DSB
. Other then a 3-4" Porc. Puffer I have a decent sized domino damsel and a rusty dwarf angel. Inverts are a red brittle star and large black long spine urchin. I think one peppermint is still in here from before I had a large Mantis get in and clean house. I got it out now, it was 2-3 inchs of mean.
I know some people have puffers that never nip at shrimp or crabs but mine is not as nice to his fellow tank mates. I have a red brittle star that it picks at when it can get to it. I have not seen it go after the urchin at all.
I want to get something to clean the sand and pickup the spare food that gets past the fish. I feed then a mix of different frozen foods. Some gets eaten right away and some sneaks past them.
Are Cucumbers and another urchin a good option. Or are there any good bottom dwellers that can pick up after these.
I have a large protein skimmer btw
. I also know that 2 years or so down the line the Puffer will get to big for this tank so you don't need to post that.
