Making your own fish food Husbanding saltwater fish is an eye-wateringly expensive pastime, in part due to the cost of the fish food purchased from speciality shops. For the past year I have been feeding my fish with home-made food. The results have been very positive: perky, colourful fish and...

Inexplicable algae: 8 month-old 500-litre tank, sump and protein skimmer. Water is crystal-clear. I've just measured Ph 8.0 (I've added a bit of buffer to get back to 8.2), NO2 0.05, No3 0, NH4 0, PO4 0, Ca 320ppm. Fish are lively and in perfect health, I feed them a varied diet every other...

I have a new Protoeaster lincki, radius about 5cm, gorgeous. Any suggestions on how and what to feed him? TIA :D

I acquired a Sohal Tang 2 weeks ago, he's about 10cm. He's sharing the QT with a Bangaii cardinal, who's been there 3 weeks. The ST has been eating well and looks fine. Water parameters are all OK (zero) 26°, 1.021. Today I notice the ST a little agitated, scratching his mouth/gills and dorsal...

I got a BC last wednesday (5 days ago) and installed him alone in my QT. He's very timid, hiding under a rock all day. I've tried all manner of foods, garliced them, everything, he doesn't *seem* to eat anything, at least I haven't seen him feeding... Question is, how long could he survive...

Beginner, I lost a dozen fish to ich. Now I've setup a QT and I'll be quarantining everything for 6 weeks before it goes into the main. Question: If I keep livestock in a QT for 6 weeks, is it 100% guaranteed that *all* possibililty of ich is removed? If the answer is no, is there any way to...

My main is 480 L, currently 1.023 25°, which I want to stock FOWLR. I've setup a 250L QT and wondered what would be right SG and temp. I'm thinking that slightly less saline would be easier on the fish, maybe 1.019-1.020 and 25°. I'll be quarantining fish and inverts. Any suggestions would...

My tank is 4 months old now and my nitrites won't quite drop to 0. For over a month they're hovering at 0.05ppm - not a lot but it's telling me something isn't quite right. All other parameters are perfect. I've verified the testkit with tap and RO water, it indicates 0.0 correctly for both...

I got a lawnmower blenny 5 days ago. He's about 8cm long and very timid. On the first day I saw him nibbling the LR a bit but that only lasted a day. I've tried frozen food, flakes and nori, he doesn't seem to touch anything. He stays immobile when I'm watching, but seems to move around slyly...

I've dutifully studied Marine Invertebrates (Shimek) but haven't found these things. Could anyone help me to identify them please? 1. Pacific or Caribbean scarlet cleaner shrimp (ambionensis or grabhami)? 2. About 1.6cm across 3. About 1cm high 4. About 6mm across 5. About 8mm across...

Whilst my inverts are settling in, I've have been given a 50L tank and an Eheim 440L/H canister filter, to be filled with ceramic balls and that fluffy cloth filter material (sorry, don't know the word in English). 1. Could I use this as a QT tank (i.e Is it big enough?) 2. How many juvenile...

Whilst waiting for my tank to settle, I'm thinking about how to start re-stocking. My line of thinking is that I should install an invert cleanup crew first and let them settle in. My LFS regularly has - Banded coral shrimp (stenopus hispidus) - Camelback shrimps (rhynchocinetes spp) - Fire...

Lost all 11 fish to ich a month back. After watching 5 die from suffocation I put the rest out of their misery when they showed signs of suffering. An unpleasant experience, but from which I learned a lot. Lesson: LFS may be nice and knowledgeable but they are primarily there to sell fish; thus...

Last wednesday added an anemone, a clown and a boxfish. (Quarantine is unheard of here in Switzerland). Thursday anemone hiding under a rock; let it acclimatise I say to myself. Saturday afternoon, anemone still under rock, fish a bit skitty, Pomacanthus is scratching on shells and spending...

I'm a bit confused with my test results, the figures seem too high. I've read that I should have: NH4 <0.2 ppm NO2 <0.2 ppm NO3 <0.3 ppm PO4 <=0.07 ppm but the JBL test kits I have ranges that are much higher. For example the NO3 test steps are 0, 1, 2, 5, 10, and so on, so measuring to a tenth...

*bows politely* Greetings :D I'm a complete newbie, both to aquariums and this forum, where there seems to be a lot of wise people. I'd like to ask for advice on rockscaping, as I haven't been able to find any threads on the subject. I've had built a 126-gallon FOWLR, wet-dry, sump, filled...
